1 ANNOUNCING ESS **************** The ESS Developers proudly announce the release of ESS 5.3.10 Emacs Speaks Statistics (ESS) provides an intelligent, consistent interface between the user and the software. ESS interfaces with S-PLUS, R, SAS, BUGS and other statistical analysis packages under the Unix, Microsoft Windows, and Apple Mac OS operating systems. ESS is a package for the GNU Emacs and XEmacs text editors whose features ESS uses to streamline the creation and use of statistical software. ESS knows the syntax and grammar of statistical analysis packages and provides consistent display and editing features based on that knowledge. ESS assists in interactive and batch execution of statements written in these statistical analysis languages. ESS is freely available under the GNU General Public License (GPL). Please read the file COPYING which comes with the distribution, for more information about the license. For more detailed information, please read the README files that come with ESS. 1.1 Getting the Latest Version ============================== The latest released version of ESS is always available on the web at: ESS web page (http://ess.r-project.org) or StatLib (http://lib.stat.cmu.edu/general/ESS/) The latest development version of ESS is available via `https://svn.R-project.org/ESS/', the ESS Subversion repository. If you have a Subversion client (see `http://subversion.tigris.org/'), you can download the sources using: % svn checkout https://svn.r-project.org/ESS/trunk PATH which will put the ESS files into directory PATH. Later, within that directory, `svn update' will bring that directory up to date. Windows-based tools such as TortoiseSVN are also available for downloading the files. Alternatively, you can browse the sources with a web browser at: ESS SVN site (https://svn.r-project.org/ESS/trunk). However, please use a subversion client instead to minimize the load when retrieving. If you remove other versions of ESS from your emacs load-path, you can then use the development version by adding the following to .emacs: (load "/path/to/ess-svn/lisp/ess-site.el") Note that https is required, and that the SSL certificate for the Subversion server of the R project is Certificate information: - Hostname: svn.r-project.org - Valid: from Jul 16 08:10:01 2004 GMT until Jul 14 08:10:01 2014 GMT - Issuer: Department of Mathematics, ETH Zurich, Zurich, Switzerland, CH - Fingerprint: c9:5d:eb:f9:f2:56:d1:04:ba:44:61:f8:64:6b:d9:33:3f:93:6e:ad (currently, there is no "trusted certificate"). You can accept this certificate permanently and will not be asked about it anymore. 1.2 Current Features ==================== * Languages Supported: * S family (S 3/4, S-PLUS 3.x/4.x/5.x/6.x/7.x/8.x, and R) * SAS * BUGS/JAGS * Stata * XLispStat including Arc and ViSta * Editing source code (S family, SAS, BUGS/JAGS, XLispStat) * Syntactic indentation and highlighting of source code * Partial evaluation of code * Loading and error-checking of code * Source code revision maintenance * Batch execution (SAS, BUGS/JAGS) * Use of imenu to provide links to appropriate functions * Interacting with the process (S family, SAS, XLispStat) * Command-line editing * Searchable Command history * Command-line completion of S family object names and file names * Quick access to object lists and search lists * Transcript recording * Interface to the help system * Transcript manipulation (S family, XLispStat) * Recording and saving transcript files * Manipulating and editing saved transcripts * Re-evaluating commands from transcript files * Help File Editing (R) * Syntactic indentation and highlighting of source code. * Sending Examples to running ESS process. * Previewing 1.3 Requirements ================ ESS has been tested with * R >=0.49 * S-PLUS 3.3-4, 4.5, 2000, 5.0-1, 6.0-2, 7.0, 8.0 * S4 * SAS >=6.12 * BUGS 0.5, 0.6 * JAGS 1.0 * Stata >=6.0 (command line only) on the following platforms * Linux/x86 (all) * Solaris (all) * MS Windows 98/NT/2000/XP (R, S-PLUS, SAS interactive only, and BUGS) * Apple Mac OS X 10.4-5 (R, JAGS, Stata) with the following versions of emacs * GNU Emacs 20.3-7, 21.1, 21.3-4, 22.1 * XEmacs 21.4.0-8, 21.4.9-13(1), 21.4.14-15, 21.4.17-21 (betas not supported, but 21.5.23+ may work) ---------- Footnotes ---------- (1) require the files.el patch to revert-buffer for the Local Variables updating problem 1.4 Stability ============= Versions 5.3.x are meant to be release-quality versions. While some new features are being introduced, we are cleaning up and improving the interface. We know about some remaining documentation inconsistencies. Patches or suggested fixes with bug reports are much appreciated! 1.5 Mailing List ================ There is a mailing list for discussions and announcements relating to ESS. Join the list by sending an e-mail with "subscribe ess-help" (or "help") in the body to ; contributions to the list may be mailed to . Rest assured, this is a fairly low-volume mailing list. The purposes of the mailing list include * helping users of ESS to get along with it. * discussing aspects of using ESS on Emacs and XEmacs. * suggestions for improvements. * announcements of new releases of ESS. * posting small patches to ESS. 1.6 Reporting Bugs ================== Please send bug reports, suggestions etc. to The easiest way to do this is within Emacs by typing `M-x ess-submit-bug-report' This also gives the maintainers valuable information about your installation which may help us to identify or even fix the bug. If Emacs reports an error, backtraces can help us debug the problem. Type "M-x set-variable RET debug-on-error RET t RET". Then run the command that causes the error and you should see a *Backtrace* buffer containing debug information; send us that buffer. Note that comments, suggestions, words of praise and large cash donations are also more than welcome. 1.7 Authors =========== * A.J. Rossini (mailto:blindglobe@gmail.com) * Richard M. Heiberger (mailto:rmh@temple.edu) * Kurt Hornik (mailto:Kurt.Hornik@R-project.org) * Martin Maechler (mailto:maechler@stat.math.ethz.ch) * Rodney A.

See the GNU General Public License in the file COPYING in the same directory as this file for more details. 1.9 New Features ================ Changes/New Features in 5.3.10: * Fixed noweb-mode bug accidentally introduced into 5.3.9 * In noweb-mode, e.g., Rnw-mode, electric "<" also inserts closing "@". Further, the code chunk boundaries are better kept up-to-date, such that code[R] <-> text[LaTeX] minor mode switching should happen more reliably. * In noweb-mode, fix a buglet in rare [Enter] or [Tab] behavior; further, by default disable the former `[[' .. `]]' code-protection-when-filling behavior which has been found to be buggy. Changes/New Features in 5.3.9: * ESS[SAS]: evince PDF viewer now supported as well; search order: evince, Xpdf, Adobe/Acrobat Reader * ESS[R]: added support for Roxygen, potentially to be extended. * ESS[S] (and R): inferior (`*R*') and transcript modes no longer fontify language keywords (such as `for', `in', etc). * iESS[Stata]: Customize the `ess-sta-delimiter-friendly' setting to t to convert embedded semi-colons to newlines for Stata processing. * Sweave fix for embedded blanks in PDF reader and PDF files * Several fixes for Major Mode Convention violations in `ess-mode' and `noweb-mode'. * ESS[JAGS]: `M-x comment-region' now available! * ESS[S] The `ess-swv-*' commands (and keybindings) are now in a submenu of the "Noweb" menu, when editing Sweave files. Changes/New Features in 5.3.8: * ESS[JAGS]: more separation from ESS[BUGS] (as much as is currently planned); now `C-c C-c' on an empty `.jmd' creates a template as it should; symbolic links are created for CODA output so BOA is happy: from `index.txt' to `.ind' and `chain#.txt' to `#.out' * ESS[SAS]: buffer-local `ess-sas-submit-command' and `ess-sas-submit-command-options' now recognized by `ess-sas-submit-region' * ESS[S]: When trying to evaluate code in an S language buffer and there is no associated process, now start R automatically instead of signalling an error. Also, restart R if there is an associated process which is not running. However, do not start R just via the "electric" `(' (`ess-r-args-auto-show'). * ESS[S]: For (one-line) functions withOUT '{ .. }' bodys, the end of function is now correctly found more often. This notably improves `C-c C-c' (`ess-eval-function-or-paragraph-and-step'). * ESS[JAGS]: cleanup/re-organization of elisp code; symbolic links for CODA output are now only created by the new JAGS `system' command in version 1.0.3; specify whether this command is available via `ess-jags-system'; if not present, then no links are created so that the `*shell*' buffer does not become unresponsive during the batch run Changes/New Features in 5.3.7: * ESS: `ess-default-style' now *is* customizable, i.e., changing its value in `~/.emacs' now does have the desired effect. * ESS: `ess-font-lock-mode' is a new variable (default: t) which controls whether font-locking is enabled in ESS buffers. * ESS[R]: for XEmacs on Windows; another tweak to find R versions * ESS[SAS]: font-locking updated for ODS and SAS Bayesian Procedures; a more consistent handling of SAS options by `ess-sas-submit-command-options' which is buffer-local; portable snooze for MS Windows via customize-able `ess-sleep-for' (floats welcome); Xpdf now supported as a PDF viewer * ESS[Rnw]: now also works with "emacs -nw" and Emacs 22. * ESS[JAGS]: now requires JAGS 1.0 (see the new ESS for JAGS help section for more information): both need work; suggestions welcome * ESS[R]: [TAB] completion now uses the R-internal completion mechanism (for R >= 2.5.0). * ESS[R] ([S]): interpretation of "_" as assignment has been removed in `ess-continued-statement-p' for R and S. * several internal code cleanups. * ESS[R]: An experimental version of a new command `Rgui' on MS Windows to send lines directly from emacs to `Rgui' is available in file `lisp/essd-rgui.el'. Preliminary documentation is in file `doc/rgui-doc.txt'. Changes/New Features in 5.3.6: * ESS: for XEmacs, using "gnuclient" (without a "-q") works for things like fix() after M-x gnuserv-start has been done. * ESS[R]: M-x R-newest should now work in more situations on MS Windows, e.g., when R has been installed in a non-default "ProgramFiles" directory tree. In these cases, there's no need to specify the name (and full path) of the R program anymore. * ESS[R]: For XEmacs, startup (with new tooltip code) works again. Changes/New Features in 5.3.5: * ESS[R] a new defun is available, `M-x R-newest', which will start the newest version of R that it can find on your system. * ESS[R] add Sven Hartenstein's "R function arguments tips" functionality, via new file `../lisp/essd-r-args.el'. Note that this includes an "electric "("" behavior inside `R-mode' which is _active by default_ and can be customized via `ess-r-args-electric-paren'; i.e., use `(setq ess-r-args-electric-paren nil)' to turn it off. Further, `ess-r-args-show-as' allows to switch to the "tooltip" mode. * ESS: functions `ess-get-pdf-viewer' and *-ps-viewer; built on new customizable variables `ess-pdf-viewer-pref' and `ess-ps-viewer-pref'; currently used in `ess-swv-PDF' and `*-PS'. * ESS[R] Improved `ess-swv-PDF' to run pdf viewer only if pdflatex was ok * ESS[R] Improved `ess-swv-weave' to start R automatically if none is running. * ESS: Do no longer ask _which_ ESS process to use if there is only one. Changes/New Features in 5.3.4: * ESS[R] now better work with options(error=recover); and the new default of CHM help files on windows. * ESS[R] some more cleanup in the "sweave" functions * miscellaneous fixes Changes/New Features in 5.3.3: * ESS[S] fix buglet (5.3.2 only) which left command prompt in "execute buffer" and hence help files. * new customizable variable `ess-display-buffer-reuse-frames' set to true (which changes default behavior) such that execution or help *frames* are reused. Changes/New Features in 5.3.2: * Classic BUGS now supported by `(require 'essd-bugs)' with ESS[BUGS] and JAGS by `(require 'essd-jags)' with ESS[JAGS]. But, only one of them can be used at a time since they don't play nice together. Also, `C-c C-c' is now bound to the function `ess-bugs-next-action' (`F12' has been retired). And finally, note that `essl-bug.el' is deprecated and the replacement is `essl-bugs.el'. * ESS[R] Improved some of the "Sweave-make" functions (yet scarcely documented) in `ess-swv.el'. * ESS[S] No longer mess with .Last.value (nor in other "languages"). Changes/New Features in 5.3.1: * See the docs for 2 ways to install ESS for XEmacs 1. by uncommenting the XEmacs part of Section 1 of `Makeconf' and performing `make install' 2. by unpacking either `ess-5.3.1.tgz' or `ess-5.3.1.zip' into `PREFIX/lib/xemacs/site-packages' on unix or `PREFIX\XEmacs\site-packages' on windows * ESS[R]: fixed bugs so that Rterm.exe can be found by XEmacs * ESS[S]: `ess-toggle-S-assign-key' is slightly changed; in particular, the default `ess-assign-key' is now `C-x ='. * ESS[R]: `M-x R-site-search' is a new (slightly experimental) utility similar to R's `RSiteSearch(..)' but with the advantage of using Emacs' preferred browser, see `browse-url-browser-function' Changes/New Features in 5.3.0: * ESS[BUGS]: sanely re-format statistical output, `.bog', from scientific notation to numbers rounded with 4 decimal places with `M-x ess-bugs-sci-round-to-4-dp'. * The keys for navigating among section headings in help buffers worked, but only for one language per session; they should now work for multiple languages. (They were also broken on Windows machines.) * ESS[S] long standing buglets in the internal logic for loading lisp code on Windows. Particularly fixed behavior in help mode with S-plus GUI. * New variable, `ess-use-inferior-program-name-in-buffer-name', which enables using the executable name instead of the dialect name for R. Feature request. * ESS[S] `ess-execute-screen-options' now also works correctly when there is more than one window *side-by-side* in the same frame and runs in the correct buffer also when there is more than one S buffer. * iESS[S] new functions `ess-eval-paragraph-and-step' and `ess-eval-function-or-paragraph-and-step' are bound to keys `C-c C-p' and `C-c C-c' respectively and to the menu in ESS-mode; also bound in the help mode (for evaluating examples). * ESS[S] new function `ess-toggle-S-assign-key' allows to assign the " <- " insertion to an arbitrary key. Changes/New Features in 5.2.12: * ESS[SAS]: `M-;' fixed, but the XEmacs function `comment-dwim' may be broken, if so, use `M-x comment-region' and `M-x uncomment-region' instead; only valid PROCs are fontified which is very helpful finding syntax errors (currently supported: BASE, ETS, FSP, GRAPH, IML, INSIGHT and STAT); the "feature" where `F'-keys take you to an empty buffer when the requested destination is a file that does not exist has been fixed, now the request results in a no-op. Further, sas-mode now also works in simple terminals. * Rterm/Cygwin combination works under Microsoft Windows. * ESS[R]: internal calls use baseenv() instead of NULL and define 'baseenv' where needed. * New experimental support for installing ESS. See the file `lisp/ess-install.el'. Changes/New Features in 5.2.11: * ESS Info entry and `dir' handled more effectively for GNU Emacs users * ESS[SAS]: temporary files created for batch submission of a region are now named based on the current file; see `ess-sas-file-root' for details; all `lag' and `dif' functions now fontified correctly * iESS[SAS]: fixed a few nagging bugs, however, still does not appear to work at this time; please let us know if you have any ideas. * ESS[S]: Support for running other versions of Splus has been added for unix. Two new variables, `ess-s-versions' and `ess-s-versions-list', are used to tell ESS what other versions of Splus you would like to run. Changes/New Features in 5.2.10: * ESS[R]: ess-r-versions can no longer be customized (since the customization was not taking effect unless customizations were loaded before ESS). Its value has been changed so that it will also find R executables beginning "R-devel" and "R-patched". If you wish to change this variable, it must be set in your `.emacs' before ESS is loaded. * Installation with GNU Make enhanced: unix and unix-like operating systems will now be able to install ESS for all users in either a GNU Emacs site-lisp or an XEmacs package configuration by editing `lisp/ess-site.el' and `Makeconf' accordingly, then issuing `make install' * ESS[S]: Filename completion (inside strings) now also works in XEmacs for R and S-plus. Changes/New Features in 5.2.9: * ESS[R] for Windows: the \ directory character bug with respect to ess-load-file has been eradicated. * iESS[SAS]: `C-c C-r' and `C-c C-b' once again work as intended and documented. * ESS[S]: M-x ess-fix-EQ-assign is a bit more agressive. * ESS[S]: Imenu now also shows setAs(), etc. * ESS[R]: R function pattern enhanced with underlying code such that `M-C-a' (`ess-beginning-of-function') etc now work for many more cases, including S4 method definitions. * iESS[R]: myOwnhelp(1) no longer wrongly triggers help(1). * ESS[R]: Improved detection of bogus help buffers: valid help buffers containing with the string "no documentation"(e.g. contour) were being treated as bogus. * ESS[R]: In R help buffers, if `options("help.try.all.packages" = TRUE)' then `?rlm' will list which packages rlm is defined in. This help buffer is not bogus, but instead is now relabelled "*help[R](rlm in packages)*". * ESS[STA]: add "//" as comment starting character to syntax-table. Changes/New Features in 5.2.8: * iESS: [Tab] completes *file* names "inside string" as in earlier (<= 5.2.3) ESS versions. Changes/New Features in 5.2.7: * If you use Custom to change the variable ess-toolbar-items, the new toolbar is used in all subsequent ESS buffers. * ESS[SAS]: new feature: if ess-sas-log-max >0 and your .log grows to more than ess-sas-log-max bytes, just the first ess-sas-log-max bytes are refreshed; this is helpful when your .sas program generates lots of error messages and gets too big for emacs to display * ESS[R/S]: `M-;' in R/S editing modes will now indent with either one or two hashes depending on context. * ESS[R]: David Whiting's Sweave extensions (to 'noweb') are now available (from ess-swv.el loaded by default). Changes/New Features in 5.2.6: * Removed non-ASCII characters in a few files. * ESS[R]: now works better when UTF-8 locale is active; in particular, you get correct directional quotes in R's startup message for R-devel (unstable development version of R 2.1.0) when using environment variables LANGUAGE=en@quot LC_ALL=en_US.UTF-8 * ESS[SAS]: toggling of .log mode improved (`F10'); toggling of .lst mode now also available (`C-F10'); killing all buffers associated with .sas program no longer bound to `C-F10' since its a bit overzealous. * S-Plus 7 for Windows is now recognized. * ESS[S] (incl. R): in auto-fill mode, strings are not wrapped anymore. * ESS[S] (incl. R): font-lock now correctly differs between R and S, e.g., for "_"; both now fontify warning(.) and S does terminate() additionally. * Support for `bell' aka `beep' aka `ding' aka `alarm' in all inferior modes: When \a is output "to the the console" at the beginning of a line, the bell is rung. Changes/New Features in 5.2.5: * ESS[R]: `C-c C-q' or `Quit S' from the menu now should work (again and less klunkily) and do not append `-exited' to the buffer name. Further, the behavior of `(ess-cleanup)', called from ess-quit, now depends on the new customizable variable `ess-S-quit-kill-buffers-p' which defaults to `nil'. Consequently, the question _"Delete all buffers associated with ..?"_ will not be asked anymore by default. * ESS[SAS] - ess-ebcdic-to-ascii-search-and-replace will now work with the `recode' application as well which is available on many platforms * ESS[S] (incl. R): Name completion for slots of S4 objects now works! Changes/New Features in 5.2.4: * The documentation now includes an overview of how to use the emacs TAGS facility for S functions. (The distribution also used to contain a directory `etc/other/Tags' where a ~1990 version of `etags.c' was distributed; this is no longer relevant and so has been deleted.) * ESS[SAS] - When you are working with EBCDIC files on an ASCII platform, .log NOTEs may display as gibberish since the EBCDIC characters are not converted to ASCII prior to their display. So, the function ess-ebcdic-to-ascii-search-and-replace is provided for convenience and is bound to `C-F11'. This function requires the `dd' command (only available on unix or unix-like platforms). * ESS: Completion of object names is now always done dynamically rather than allowing the option of using a pre-computed database (by `ess-create-object-name-db') since modern computers seem fast enough for dynamic completion. (We expect few users, if any, have been using the pre-computed database method.) * ESS: object completion in iESS buffers running on Windows was very slow (for GNU Emacs, but not XEmacs) and has now been fixed. Further, it was more or less broken for all versions of S-plus 6.x, and has been fixed to work everywhere but with the Windows' GUI of S-plus. The list of objects now shows unique names also when an object appears more than once in the search path. * ESS[R]: Completion of object names now also includes those starting with ".". Changes/New Features in 5.2.3: * ESS: When new inferior ESS processes are created, by default they will replace the current buffer (this restores behavior from pre 5.2.0). If you wish new ESS processes to start in another window of the current frame, set inferior-ess-same-window to nil. * New variables inferior-Splus-args and inferior-R-args provide a way to pass command line arguments to starting S and R processes. Changes/New Features in 5.2.2: * bug-fixes for 5.2.1 (require 'executable), html docs, etc. * ess-lisp-directory/../doc/info added to Info-directory-list if ess-info not found by info * ESS[R]: If you have other versions of R on your exec-path, such as "R-1.8.1" with Unix or "rw1081" with Windows, ESS will find them and create appropriate functions, such as `M-x R-1.8.1' or `M-x rw1081', for calling them. By default only Unix programs beginning "R-1" and "R-2" and Windows programs parallel to the version of R in your exec-path will be found, but see ess-r-versions and ess-rterm-versions for ways to find other versions of R. * ESS[R]: Other versions of R, such as "R-1.8.1" on Unix and "rw1081" on Windows, are added to the "ESS / Start Process / Other" menu. * ESS[S]: If you have other versions of S-Plus on your Windows computer, such as S-Plus 6.1 or S-Plus 4.5, ESS will find them and create appropriate functions, such as `M-x splus61', for calling the console version (Sqpe) inside an emacs buffer. By default only programs installed in the default location will be found, but see ess-SHOME-versions for ways to find other versions of S-Plus. * ESS[S]: Other versions of Sqpe on Windows, such as "splus61", are added to the "ESS / Start Process / Other" menu. * ESS[R]: (bug fix) ess-quit (bound to `C-c C-q') should now quit the inferior R process, when issued from either the inferior buffer, or from a .R buffer. Changes/New Features in 5.2.1: * ESS[S] (R and S-plus): now have toolbar support with icons to evaluate code in the inferior process or to switch there. This code is experimental and likely to change as XEmacs/Emacs issues get resolved. The toolbar should be enabled if your Emacs displays images, but can be disabled with the variable ess-use-toolbar. Thanks to David Smith from Insightful for the S-plus logo. * ESS[SAS]: ess-sas-graph-view (`F12') enhanced; you can specify external file viewers for each graphics file type via the alist ess-sas-graph-view-viewer-alist; also .jpg/.gif are now handled by image-mode on XEmacs, if available, otherwise by graphics primitives as before Changes/New Features in 5.2.0: * ESS[BUGS]: new info documentation! now supports interactive processing thanks to Aki Vehtari (mailto:Aki.Vehtari@hut.fi); new architecture-independent unix support as well as support for BUGS v. 0.5 * ESS[SAS]: convert .log to .sas with ess-sas-transcript; info documentation improved; Local Variable bug fixes; SAS/IML statements/functions now highlighted; files edited remotely by ange-ftp/EFS/tramp are recognized and pressing SUBMIT opens a buffer on the remote host via the local variable ess-sas-shell-buffer-remote-init which defaults to "ssh"; changed the definition of the variable ess-sas-edit-keys-toggle to boolean rather than 0/1; added the function ess-electric-run-semicolon which automatically reverse indents lines containing only "run;"; `C-F1' creates MS RTF portrait from the current buffer; `C-F2' creates MS RTF landscape from the current buffer; `C-F9' opens a SAS DATASET with PROC INSIGHT rather than PROC FSVIEW; "inferior" aliases for SAS batch: `C-c C-r' for submit region, `C-c C-b' for submit buffer, `C-c C-x' for goto .log; `C-c C-y' for goto .lst * ESS[S]: Pressing underscore ("_") once inserts " <- " (as before); pressing underscore twice inserts a literal underscore. To stop this smart behaviour, add "(ess-toggle-underscore nil)" to your .emacs after ess-site has been loaded; ess-dump-filename-template-proto (new name!) now can be customized successfully (for S language dialects); Support for Imenu has been improved; set ess-imenu-use-S to non-nil to get an "Imenu-S" item on your menubar; ess-help: Now using nice underlines (instead of `nuke-* ^H_') * ESS[R]: After (require 'essa-r), `M-x ess-r-var' allows to load numbers from any Emacs buffer into an existing *R* process; `M-x ess-rdired' gives a "directory editor" of R objects; fixed ess-retr-lastvalue-command, i.e. .Last.value bug (thanks to David Brahm) * ESS: Support for creating new window frames has been added to ESS. Inferior ESS processes can be created in dedicated frames by setting inferior-ess-own-frame to t. ESS help buffers can also open in new frames; see the documentation for ess-help-own-frame for details. (Thanks to Kevin Rodgers for contributing code.) Changes/New Features in 5.1.24: * The version number is now correct even inside ESS/Emacs Changes/New Features in 5.1.23: * Minor more Makefile clean up. Changes/New Features in 5.1.22: * Besides info documentation, PDF and HTML documentation are also provided (instead of built using "make") and available on the web as well; see ESS web page (http://ess.r-project.org/) and StatLib (http://lib.stat.cmu.edu/general/ESS/doc) * Now that info documentation is available, the README.* files are no longer supported. However, they are still distributed for what it's worth. * ESS is now an XEmacs package! See XEmacs Installation HOWTO (http://www.xemacs.org/Install/index.html) for details (specifically, items 10-15). * ESS[SAS]: more user-friendly enhancements for remote SAS batch jobs with Kermit file transfers (LOG and OUTPUT function key features now supported). Multiple shells now supported so you can run SAS on different computers from different buffers by setting the buffer-local variable ess-sas-shell-buffer to unique buffer names. * Major re-vamping of Makefile/Makeconf. Changes/New Features in 5.1.21: * ESS[SAS]: info documentation now available!, see ESS->Help for SAS; `F12' opens GSASFILE nearest point for viewing either within emacs, when available, or via an external viewer; more syntax highlighting keywords; more enhancements for remote SAS batch jobs with Kermit; new framework for remote SAS interactive jobs, see ess-remote * ESS[S]: info documentation now available!, see ESS->Help for the S family * Makefile: tag now independent of rel; info files made by doc/Makefile and installed in new info sub-directory Changes/New Features in 5.1.20: * New `options()$STERM' in the S dialects (S, S-Plus, R). The S program can determine the environment in which it is currently running. ESS sets the option to `iESS' or `ddeESS' when it starts an S language process. We recommend other specific values for S language processes that ESS does not start. * New `ess-mouse-me' function, assigned to S-mouse-3 by default. User may click on a word or region and then choose from the menu to display the item, or a summary, or a plot, etc. This feature is still under development. * GNU Emacs 21.1 is now supported (fixed for S dialects, SAS & BUGS), (some from Stephen Eglen). * XEmacs 21.x is now supported (fixed w32-using-nt bug) * XEmacs on Win (NT) is better supported. * Workaround for bug in Sqpe+6 (S-PLUS 6 for Win). * should now work even when imenu is not available (for old XEmacsen). * ESS[SAS]: XEmacs-Imenu fix; `C-TAB' is globalized along with your function-key definitions, if specified; you can specify your SAS library definitions outside of autoexec.sas for ess-sas-data-view with SAS code placed in the variable ess-sas-data-view-libname, also the dataset name is defaulted to the nearest permanent dataset to point; Speedbar support now works for permanent datasets, please ignore first./last.; new font-locking is now the default with more improvements for font-locking PROCs, macro statements, * ; and %* ; comments; you can toggle sas-log-mode with `F10' which will font-lock your .log (if it isn't too big); submit remote .sas files accessed with ange-ftp, EFS or Tramp (Kermit is experimental) by setting ess-sas-submit-method to 'sh; ess-sas-submit-command and ess-sas-submit-command-options are buffer-local so you can have local file variable sections at the end of your .sas files to request different executables or specify special options and the local file variables are re-read at submit instead of only at file open so that if you make a change it is picked up immediately; * ESS[BUGS]: font-lock with `in' fixed. * for STATA: font-lock bug fixed. * for Rd mode: `C-c C-v' and `switch-process' in menu. further, `C-c C-f' prefix (Rd-font) for inserting or surrounding a word by things such as \code{.}, \code{\link{.}}, \emph{.} etc. * new functions (ess-directory-function) and (ess-narrow-to-defun) ess-directory <-> default-directory logic (Jeff Mincy). * Re-organized Makefile and fixed a few bugs. Changes/New Features in 5.1.19: * S+6 now supported (Tony Rossini (Unix) and Rich Heiberger (Windows)) * New BUGS support through ESS[BUGS] mode (Rodney Sparapani) Templates assist you in writing .bug and .cmd code (.cmd and .log are replaced by .bmd and .bog to avoid emacs extension collisions). Substitution" parameters facilitate "automagic" generation of data...in" and "init...in" filenames, "const N=" from your data file and "monitor()/stats()" commands. Activated by pressing `F12'. * Fixes for `ess-smart-underscore' SAS breakage (Rich Heiberger) * You can change between PC and Unix, local and global SAS function-key definitions interactively (Rich Heiberger) * `C-Submit' a highlighted region to SAS batch (Rodney Sparapani) * New and improved SAS syntax highlighting (Rodney Sparapani) To get the new functionality, set ess-sas-run-make-regexp to nil. Also available in .log files via `F10'. * Open a permanent SAS dataset for viewing via `F9' (Rodney Sparapani) You must have the library defined in autoexec.sas for it to work. * User-friendly defaults for `sas-program', `ess-sas-batch-pre-command' and `ess-sas-batch-post-command' as well Customize support for these and other ESS[SAS] variables (Rodney Sparapani) * `ess-sas-suffix-2' now defaults to .dat via `F11' (Rodney Sparapani) * Emacs/XEmacs, Unix/Windows issues collectively handled in ess-emcs.el * defadvice solves problem of missing *ESS* (thanks to Jeff Mincy) * Improved manual a bit by including things that were only in `README'. Changes/New Features in 5.1.18: * New `ess-smart-underscore' function, now assigned to "_" by default. Inserts `ess-S-assign' (customizable " <- "), unless inside string and comments where plain "_" is used instead. (MM) * Fixes for longstanding interactive SAS breakage (RMH) Changes/New Features in 5.1.17: * Documentation for Windows Installation (Rich Heiberger) * removal of ess-vars, finalization of customize support (in the sense that there is no more use of ess-vars, but that we need to fix ess-cust) (AJ Rossini) * Many small (and large) fixes/contributions (MMaechler) * addition of the "S-equal" variable and provide `M-x ess-add-MM-keys' a way to remap "_" to `ess-S-assign', typically " <- ", but customizable. (MMaechler) Changes/New Features in 5.1.16: * BUG FIXES * Better SAS support Changes/New Features in 5.1.15: * BUG FIXES Changes/New Features in 5.1.14: * Yet more fixes to SAS mode, (Rich Heiberger and Rodney Sparapani) * Customize support (for most Emacsen which support it) (AJRossini) * ARC and ViSta support out of the box, and fixes for XLispStat (AJRossini) Changes/New Features in 5.1.13: * Version numbering finally all depending on the ./VERSION file, thanks to Martin Maechler. * Yet more fixes to SAS mode, thanks to Rich Heiberger. Changes/New Features in 5.1.12: * Splus 5.1 stabilized, thanks to Martin Maechler, Bill Venables, Chuck Taylor, and others. * More fixes to SAS mode, thanks to Rodney Sparapani and Rich Heiberger. Changes/New Features in 5.1.11: * More fixes to Stata mode, thanks to Brendan Halpin (mailto:brendan@essex.ac.uk). * fixed bugs in ESS-elsewhere, thanks to many testers * README.SPLUS4WIN has DETAILED instructions for S-PLUS 2000, thanks to David Brahm (mailto:brahm@alum.mit.edu). * Fixes to SAS mode, thanks to Rodney Sparapani Changes/New Features in 5.1.10: * More fixes to Stata mode * primitive generic version of ESS-elsewhere * Small fixes to SAS/Stata. Changes/New Features in 5.1.9: * Stata mode works * Literate Data Analysis using Noweb works Changes/New Features in 5.1.8: * Bug fixes * R documentation mode defaults changed Changes/New Features in 5.1.2: * able to use inferior iESS mode to communicate directly with a running S-Plus 4.x process using the Microsoft DDE protocol. We use the familiar (from Unix ESS) `C-c C-n' and related key sequences to send lines from the S-mode file to the inferior S process. We continue to edit S input files in ESS[S] mode and transcripts of previous S sessions in ESS Transcript mode. All three modes know the S language, syntax, and indentation patterns and provide the syntactic highlighting that eases the programming tasks.
