ANNOUNCING ESS ************** The ESS Developers proudly announce the release of ESS 5.1.23 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.

If you have GNU Emacs 19.29, see *Note Unix installation::. Stability ========= Versions 5.1.x are meant to be gamma-level releases. While some bugs are fixed, others may have been introduced, especially with regards to new features. See the file doc/TODO for details. Bug reports are solicited; see the Bugs Section below. Patches or suggested coding fixes with bug reports are much appreciated! 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. 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.

New Features ============ Changes/New Features in 5.1.23: * The version number is now correct even inside ESS/Emacs * 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://software.biostat.washington.edu/ess/doc) 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.
