CHANGES.

rw2000

======

The miniR distribution no longer included compiled HTML help (to stop

it needing 10 floppies rather than 7).

Added Rgui script editor by Chris Jackson.  Supports object name

in window caption in edit() and fix().

Changed preferences menu button "Finish" to "OK".

Changed search order for user home directory to use "My Documents" 

directory after HOME and before HOMEDRIVE/HOMEPATH.

Added functions setWindowTitle(), getWindowTitle(), and 

getIdentification().

Added function getWindowsHandle().

The windows() device has a new 'bg' argument to set the background

colour (which still defaults to "transparent").

The C headers files are now installed into R_HOME/include rather than

R_HOME/src/include (as on Unix).

choose.files() now expands '~' to the user's home directory, as 

most other file system functions do.

(For those building R:) The Makefile now aborts if sub-makes in any of

several for-loops fail.

R BATCH|SHLIB|INSTALL|REMOVE no longer work: use Rcmd or R CMD (as

required under Unix) instead.

Rcmd INSTALL now does a `safe installation': it moves away any

existing installation of the packages, and moves them back if it

fails.  In any case, a failed installation is removed.  Bundles are

processed differently, by combining the DESCRIPTION and DESCRIPTION.in

files and processing each package separately.  Installation of a

bundle now fails as soon as installing any component package fails.

It is possible to install the current directory by `Rcmd INSTALL .' .

winMenuAdd() and winMenuAddItem() now allow addition of menu items to

the console and graphics windows and their popup menus.  Repeated

addition of the same menu no longer leads to duplicate menus.

winMenuDel() now deletes all submenus and items within the menu.

Building a complete distribution has an extra step, as the grid

vignettes depend on lattice (and so were incomplete in R 1.9.x on both

Unix and Windows).

The manual way of building packages is now deprecated, and it is no

longer possible to use it to build bundles (which was never documented).

Cross-building of packages is now done by the XINSTALL script.

bringToTop() in MDI mode now brings the whole MDI frame to the top

before raising the chosen window within it.

There is a new utility to check the installation (not miniR.exe).

Open a Command Prompt/MS-DOS window, cd to the top of the installation

(where the READMEs are) and run

	bin\md5check MD5

Any changed or missing files will be reported.  You can also

double-click to run the file -- it will open a window which will stay

open if there are any errors and close quickly otherwise.

The `Manuals' menu item in RGui is renamed to `Manuals (in PDF)', and

is now greyed out if no manuals are present (which GraphApp was not

doing correctly).

There is a new component in the main installer for the sources of the

help pages (the man subdirectories of the libraries) -- these were

not installed under Windows before.

The RGui menu item for installing packages from CRAN make uses of the

(non-default) setting of install.packages(dependencies = TRUE) to fetch

all the other packages needed to run those specified.

Improvements to file("clipboard") connections -- see ?file plus some

more warnings e.g. if the clipboard becomes full.

Memory leaks were fixed in rproxy.dll (used in (D)COM).  A break

to the debugger during rproxy.dll startup may be triggered by setting 

the DEBUG_RPROXY environment variable.

rw1091

======

Installing a package with a saved image was not exiting on an error

making the image (PR#6769).

Installing a package which failed did not return an error code from

Rcmd INSTALL (PR#6768).

choose.files(multi=FALSE) was liable to give incorrect results (PR#6818).

Workaround for bug in Microsoft critical update KB835732:  if HOMEPATH

environment variable is not set properly, R would not start (PR#6802).

Under ESS, Rterm could freeze when quitting (PR#6812).

The file.show() internal code failed to close its FindFirst handle and

so the directory on which it was used (often the R temporary

directory) could not be deleted from within R.

If a graphics window is opened in a minimized MDI session, it now

uses the physical monitor size instead of the zero-sized MDI frame.

Using PgUp whilst recording after a multiple of 4 plots failed to save

the current plot. (PR#3663 revisited.)

It is now possible to install a package with a man file called (INTRO).Rd.

rw1090

======

Both Rterm and Rgui now give usage information via the --help or -h

command-line flag.

There is now a "Misc|Break to debugger" menu option, enabled 

when a debugger is detected (somewhat fallibly), or infallibly by the

"--debug" command line option.  This will cause a trap to an external

debugger, e.g. for running Rgui under gdb.  If the menu item is

selected when not running under a debugger R is likely to crash.

If the "--debug" option is used, R will break to the debugger during

command line processing, allowing the startup process to be debugged.

Added "stay" argument to bringToTop(), to allow the user to specify

that a window should stay on top of other windows.  Also added "stay

on top" item to the popup menus.  All of these require R to be running

in SDI mode ("Rgui --sdi" or via the settings in file `Rconsole').

Changed windows() so that new windows fit within the MDI client

area.

Added winMenuNames() and winMenuItems() functions to query user menus.

Added menu items for www.r-project.org and CRAN on the help menu. 

(Wishlist PR#6492)

Added "R" command to be similar to Unix invocation of scripts, e.g.

"R CMD INSTALL" is the same as "Rcmd INSTALL".  Rcmd still exists for 

backwards compatibility (and to avoid conflicts over the name `R').

All of R, R CMD and Rcmd now accept --help.

Rcmd Rd2dvi can now be specified as such rather than as Rcmd Rd2dvi.sh.

Added "Paste commands only" to edit and popup menus in the Rgui console.

This allows copying of a block of output, but pasting only the commands

back to the console for re-execution.  (Code contributed by Tony Plate.)

Installation

------------

Parallel make (make -j2, say) can be used, but only usefully on

dual-processor (or perhaps hyperthreaded) hosts with at least 384Mb of

memory.

Installing now sorts in the C locale to ensure that a consistent sort

order is used.  (Some aspects of sorting used to be done in the locale

of the host machine, but Perl and the cygwin-based tools used the

ASCII collation order.)

The long-untested support for making Windows .hlp files has been withdrawn.

There is support for using K. Goto's fast BLAS.  On a 2.6Ghz P4 with

1Gb RAM and A a 1000 x 1000 matrix we had the following timings

	R BLAS	ATLAS	Goto

A %*% A	 3.7	0.65	0.56

svd(A)	16.2	7.77	6.83

Note that using a fast BLAS is much less effective for smaller

matrices as are more common in statistical applications.

Faster assembler code for exponentiation is used.

Cross-building of R itself now works again.  (It had been broken since

1.8.0.)

Building/installing packages

----------------------------

R CMD INSTALL/build/check map path names with spaces in to their short

forms.

R CMD INSTALL now supports versioned install via --with-package-versions.

Installing (binary) package bundles now checks the MD5 sums and

reports success, just as for packages.

Added "* DONE" to the end of INSTALL logs so --install option to CHECK

will work. (This is a repository maintainer option; see 

src/scripts/check.in for docs).

Internal changes

----------------

The fast bmp/png/jpeg code introduced in R 1.8.0 is used even for

256-color displays (as we have now been able to test it on such).

R's internal malloc etc are now remapped to Rm_malloc etc and only

used in allocating memory for R objects, the Wilcoxon tests and a few

other memory-intensive applications.

Improved malloc routines from the current version of Doug Lea's malloc

(as suggested by David Teller) should enable large memory areas to be

used more effectively, in particular those over 2Gb where OS support

has been enabled.  The initially requested memory is no longer

reserved, but as this malloc is able to work with non-contiguous

memory chunks that should not matter.

The installer uses LZMA compression, so Inno Setup >= 4.1.5 is required.

Version 1.2.5 of libpng is now used in binary builds.

Bug fixes

---------

Fixed list.files() to properly handle paths like "C:", etc.

Fixed unlink() to accept empty file list for Unix consistency.

Fixed handling of whitespace in Rd2dvi.sh processing of DESCRIPTION

files.

Fixed handling of "--max-mem-size" syntax error on command line.

In RGui, ^T would not transpose the first and second characters on a

line.  (PR#5593)

Fixed junk character at start of a pipe(). (PR#5053)

R CMD SHLIB was computing dependencies for all C files, not just those

specified on the command line, and building the DLL from all *.o files

in the directory.

The sizes of metafiles in pixels were often coming out one pixel more

than requested, so the background was not quite all painted.  Now we

over-estimate.

Rproxy.dll would cause a crash when transferring large amounts of data.

Workaround for Microsoft's esoteric idea that date-times in 1970 before

1970-01-01 00:00:00 GMT are invalid, so as.POSIXct("1970-01-01

00:00:00") failed in timezones ahead of GMT.

Avoid possible segfault with browseURL() on urls of more than 264 chars

(although these are not guaranteed to work).

rw1081

======

Files in inst/ are installed later in the process of installing a

package (at the request of Ray Brownrigg: the build process was as

documented in `Writing R Extensions').  CVS files will not be installed.

The fast bmp/png/jpeg code introduced in R 1.8.0 is used for saving

from menus (and savePlot()) as well as for the devices.

Lines drawn at the extreme top or right of the device region (e.g. by

box(which="outer")) might have been drawn one pixel too far from the

origin and so perhaps clipped.

In 1.8.0 only, the bottom line of pixels was not copied to the file

for png/jpeg/bmp device plots (as the Windows GDI function used was

incorrectly documented).

File src/nmath/dnt.c was not being built for the standalone Rmath library.

packageStatus() now works under Windows.

Fixed instability under some Windows versions associated with

double buffering of the windows() device. (PR#5173)

rw1080

======

The initial size and position of the MDI frame can be set in Rconsole:

see the comments in .../etc/Rconsole.  The initial position of the

console window and graphics windows can be set in Rconsole and in the

GUI Preferences editor.

The windows() graphics device now has arguments xpos and ypos to set

the initial position, overriding the settings in Rconsole.

The windows() device has a form of double-buffering: the visible plot

is updated only when there has been no plotting for 0.1sec or if the

plot has not been updated for 0.5sec.  This is optional (but on by

default) and the timings can be changed: see ?windows.

The bmp/png/jpeg devices are around 10x faster when used on >8-bit

displays (but use more memory than before).

Rterm reverts to sending warning/error messages to stdout on Windows

95/98/ME.

Rcmd BATCH is now handled in C, and works again on Windows 95/98/ME.

Rcmd now sets the TEXINPUTS environment variable so that LaTeX

macros in share/texmf are available via e.g. "Rcmd latex.exe mydoc".

Calling dev.off() (or ending a session) when a windows() device is

open and recording plots automatically saves the current plot as the

last saved plot.

The windows (etc) devices use the Windows character metrics, which at

least on some systems have non-zero height and depth for space.  This

is now overridden.  (This showed up in the baseline placing for

plotmath expressions containing a space.)

A package's DLL used to be built only if standard source files were

seen.  Now src/Makefile.win is run if present, and if that generates

src/$(DLLNAME).dll the DLL is installed.  (DLLNAME is the package name

unless overridden.)

doc/manual/Makefile.win now has targets for fullrefman.{dvi,pdf}.

Added "Help | Search help..." menu item to Rgui as a front end to

help.search().

Bug fixes

---------

The changes to versioned install had ensured that the currently

installed copy of a package had its MD5 sums checked, not the version

waiting to be installed.  Now the correct version is checked.

The Copy, Paste, Copy&Paste and Kill buttons in the MDI mode failed to

restore focus to the console (see rw1070 RGui changes).

The BioConductor people had stolen the menu item for "Install

package(s) from CRAN..." so it was not being enabled/disabled

properly.

The windows() device was not plotting transparent single lines correctly.

The scrollbars on the data editor work better for very large matrices,

and correctly for more than 65535 columns.

The search for a directory for temporary files now checks that TMP and

TEMP point to actual writable directories.

PKG_FFLAGS is now used if provided.

bringToTop() tested against the wrong limit for the device list and so

would sometimes not work for high-numbered devices if lower-numbered

devices had been closed.

getwd() returns paths separated by / not \.

rproxy fixed so LAPACK gets loaded properly by (D)COM server.

Fixed installer so share/texmf files are installed with developer option.

(Sweave.sty continues to be installed in main option.)

Fixed MakePkg so that Rd files with missing line ends at EOF are corrected.

rw1071

======

The system() function printed a spurious warning when the input argument

was used.

The File|Change Dir...|Browse dialog could cause R to crash.

Fixed a bug in versioned install of binary package bundles.

Help for max.col was not being found in CHTML help: we have worked around

a bug in HHW.

The maximum allowed `pointsize' for a windows() device has been

increased to 48: some people have much bigger screens these days.

Rcmd BATCH in rw1070 incorrectly required the R::Utils Perl module.

The data editor no longer takes almost all the CPU cycles when running.

Fixed a bug in the data editor display that sometimes led to R failing

to shutdown.

Added some conditional compilation directives to the source so that the

replacement malloc() (see INSTALL) need not be used.

Changed the installer build code so that patch versions are named

rwXXXXpat.exe, development versions are named rwXXXXdev.exe, and

beta versions are named rwXXXXbeta.exe.

Fixed bugs that caused crash when windows were resized repeatedly.(PR#1711)

Changed help to use the 'title' parameter of file.show when displaying

help, for consistency with Unix versions.

Default in installer changed so a normal user installation will

include the source package installation files.

Moved the Sweave style file to the main install group.

rw1070

======

This version of R needs more memory and is slower to start up, because

it loads more packages by default.  This is only likely to be a

concern on machines with 16Mb of memory or less than 300MHz

processors.  For such machines append R_DEFAULT_PACKAGES=ctest to the

command line in the shortcut used to run R, when the memory usage will

be about equal to that of rw1062.

There is a new option to use file("clipboard") to read from or write

to the clipboard.  As most input/output functions in R use file(),

this makes it possible to read data from or write data to the

clipboard in many ways, including direct use of read/writeClipboard().

When using download.file() with the internal method and a proxy, the

user/password combination can be set to prompt the user with a

username/password dialog box, and this will be presented on proxy

authentication failure.

New function choose.files() for interactive multiple file selection.

The output from formatC() uses e+/-0n not e+/-00n for compatibility with

other platforms and with format().

A site-wide environment file R_HOME/etc/Renviron.site (or as set by

the `R_ENVIRON' environment variable) is now implemented on Windows.

The variable .SavedPlots in which plots are stored has been moved from

package:base to the user's workspace.

The warnings about changing the floating point control word are now

optional, selected by options(warn.FPU = TRUE).

The main thread is suspended briefly after Rprof() is called.  This

ensures that the timing thread gets started: on some builds and on

single-CPU machines this was not happening in 1.6.x (although it

did in 1.5.x, so it must be a compiler/runtime version issue).

Installation changes

--------------------

The installers have new options under `Additional tasks' which allow

the creation of Windows Registry entries to be de-selected by the user.

Rcmd.exe and Rprof have been moved to the main distribution (although

to use them you will need perl installed).

Tcl/Tk 8.4.1 is bundled in rw1070.exe.  You can still use your own

installation of Tcl/Tk: see the rw-FAQ.

The Makefiles that build the installers have been reorganized--see

the Maintainers.notes file for details, and INSTALL for new build

instructions.

HTML help changes

-----------------

The format of packages.html has changed, with packages listed by

library tree (as happens on Unix) when there is more than one tree.

The Java-based search index now covers all packages in all current

library trees.

When using help.start() with more than one library tree, an attempt is

made to correct the URLs in non-standard libraries which point to the

R_HOME/doc directory or to the base package.  Once this is done a

stamp `fixedHTMLlinks' is placed in the package directory, and

correction will only be done again if the R installation directory

is changed.

RGui changes

------------

The `Display file' menu item is now `Display file(s)' and allows

multiple file selection.

`Install packages from local zip files' from the `Packages' menu can

now install several files at once (by selecting multiple files in the

file selector).

Removed some calls to reset the size of the console, so it will

stay maximized throughout window operations.

The internal pager will page down with space or CTRL-F and page up

with minus or CTRL-B (key sequences which are widely used in Unix

pagers).  CTRL-A selects all the text.

The Change Directory dialog now starts in the current directory, not

always at the desktop.

RTerm changes

-------------

Rterm is now only regarded as interactive if both stdin and stdout are

a terminal: this overcomes a problem with getline.

System error messages (those which would appear in a dialog box in

Rgui) are written on stderr rather than stdout, as are R warnings and

error mesages.  If you want to capture errors as well as normal output, use

something like

	...\rterm --vanilla <foo.in >foo.out 2>&1

Installing packages

-------------------

Binary packages are retrieved from the bin/windows/contrib/1.7

directory on CRAN, so each new version will have its own set of

compatible packages.  The zip file names now include the version

number, as in mda_0.2-16.zip.

Files in the top-level directory of a source package are no longer

installed automatically: files to be installed must be put in an `inst'

sub-directory (as has long been recommended).  (The `demo' and `exec'

directories are also installed, as before.)

The BLAS library Rblas.dll is no longer automatically linked against

when building a package: as on Unix PKG_LIBS=$(BLAS_LIBS) is required

in Makevars(.win).

MD5 checksums are created on installation from sources (see

?checkMD5sums in package tools), and checked on installation by

install.packages().  If you see mismatches, this may be because files

are left over from an earlier install of the package: try deleting the

whole package directory and re-installing.

There is a new command-line flag --auto-zip to Rcmd INSTALL which

selects whether to zip up the data and/or help directories depending

on their size.  This is mainly for use with Rcmd INSTALL --build to

install and zip-up packages.

rw1062

======

New functions read/writeClipboard() to read from or write to the clipboard.

Hitting the key q (or Q) with an internal pager window in focus will

close the pager.

Source packages with a DESCRIPTION file with an incomplete last line

are now repaired.

Rcmd INSTALL tries to find canonical paths to make the check for

not installing on top of the source more foolprof.

The output when building R or source packages is much quieter.

Warnings are printed if a loaded DLL changes the floating point

control word: see ?dyn.load for the details.

Changed Windows README to README.rw1062, included standard README

and RESOURCES file in binary distribution.

Printing and copying from the menu of a graphics device now preserve

the active graphics device.

Fixed a crash that occurred when an attempt was made to view a file in

the pager but the file could not be opened (e.g. because another

application had it opened with exclusive access).

rw1061

======

Changed titles on help windows so topic name shows when minimized.

Dependencies were not being generated properly in packages using C++.

share/R/firstlib.R was not being included in the binary distribution.

rw1060

======

The installer program name has changed from SetupR.exe to rw1060.exe.

The miniR distribution has grown to eight floppies, and the zip files

are no longer distributed on CRAN.

The default memory limit has been raised to the smaller of 1Gb and the

amount of physical RAM.  (See the changes for rw1040 and rw1020 below.)

Support for bzip-ed connections has been added to the standard distribution.

update.packages() and install.packages() will not try to install a package

that is in use (with an informative warning).

Using HTML help has changed slightly: in particular

help(htmlhelp=TRUE) makes use of the setting of options("browser").

Ctrl-Z in Rgui or Rterm will signal EOF, and so can be used to

terminate a read by readLines() or scan(), for example.

bmp(), png(), jpeg() and win.metafile() devices can plot multiple

pages in separate files.

The preferred compiler is gcc-3.1: gcc-2.95.3 can still be used but

up-to-date header files are needed.

Making packages containing source code automagically makes dependency

information for C and C++ code: this is useful when experimenting with

packages, and especially for the packages which ship with R.

rw1051

======

file.rename() (which is by default used when saving workspaces) now

uses Windows API rather than ISO C functions.  This works around a

reported problem with Windows thinking a file was in use, and on

NT/2000/XP machines makes renaming an atomic operation (rather than

delete followed by move).

Bulding the standalone Rmath.dll was not making the import library

libRmath.a.

We may have been able to track down (to the isprint routine) the cause

of the FAQ Q2.14 about crashes caused by non-ASCII characters, and

hence to circumvent it.

File | Print on the menu of a windows() graphics device was not working.

The binary distribution could not make packages which needed to link

to Rblas.dll.

rw1050

======

There are few new Windows-specific features in this release: it has

been tuned to work better with Windows XP and a number of workarounds

added.

win.print() allows a printer to be specified.

help.start(browser=) is now supported: this may be useful if the

default browser does not support the Java-based search engine.

Very small circles are now forced to be visible: not all Windows

versions would display them.

Transparency in png() is now supported on `High Color' (16-bit) screens.

Changing plot resize type via the menu now works better for the current

plot (which is immediately redrawn).

BLAS support is now in a separate DLL, Rblas.dll.  This means that

packages using BLAS (KernSmooth, Matrix, bqtl, fracdiff, gss,

odesolve, quadprog, quantreg and subselect amongst those on CRAN) need

to be re-built.  The advantage is that less space is taken up overall,

and ATLAS can be used just by rebuilding Rblas.dll.

The installers now use bzip2 compression, so make smaller packages.

Cross-building automatically uses STAMP=NO for packages.

R and packages can now be built in a directory whose path contains

spaces (although we still don't recommend it).

If a package contains a script `configure.win' it will be run at the

start of installation.

Rcmd INSTALL and make pkg-foo test for attempted installation into the

source directory.

All the configuration options are now in file MkRules.

Unzipping is now handled by internal code based on zlib: unzip.dll is

no longer required.

Launching HTML files from the menus was not working with Netscape 6.2.x,

so a workaround has been provided.

Rgui.exe.manifest has been added to get XP-style widgets on Windows XP.

Some logical colour names have been changed to get consistent colour

schemes on Windows XP.

The books in the contents of CHTML for packages were not being sorted

correctly.

The floating-point control setting has been changed to use 64-bit

rather than 53-bit mantissas, which will result in slightly

different but generally more accurate results.

rw1041

======

Updating HTML indices, e.g. in help.start(), is done within a

try() construct.

help.start() has a new argument `update'.

Making packages now warns if there is a configure script.

ga.h was needed for building package `windlgs', but was omitted from the

`source package' code for rw1040.  It is now included.

Rcmd check was failing on Windows 9X, because additions in 1.4.0 were

not using Rsystem().

rw1040

======

If --max-mem-size is given a value greater than 256M, the requested

maximum memory is reserved (but not allocated) initially.  This will

enable the memory to be managed more efficiently, but does increase

the chance that R cannot be started.  There appears to be an effective

limit of about 1700M, at least under Windows 2000.

memory.limit() can now increase the memory limit of the current session.

This will not work if the limit is currently reached!

internet2.dll (see changes for rw1030) must be selected by the

--internet2 flag.

The miniR* distribution has grown to seven floppies, and no attempt is

now made to confine the zip files to floppy-size.

The background colour of a windows() window (outside the device

region) is now in the `Application Background' colour of the current

Windows colour scheme.  (It used to be LightGrey.)

Gamma correction is now applied to the background colour of a graphics

window.  (It has long been applied to the foreground colours.)  Users

of LCD screens may want to set something like gamma=2 when launching a

graphics window.

savePlot() now supports saving to PDF.

There is support for transparency in the devga device (which

encompasses screen windows, metafiles, printers and the bmp, jpeg and

png devices).  The default background colour is "transparent" for all

but the bitmap devices: this means that backgrounds are omitted when

plotting to/saving to most devices, and the colour that is visible is

that of the canvas (see below).  The png() device does support

transparent backgrounds, but this is not accessible through the menus

nor the savePlot() function.

The canvas colour of a windows() window can now be specified.  This is

is gamma-corrected, and defaults to "white".

There is a print method for saved plot histories, and individual

plots can be replayed from the command line by subsetting a

plot history variable.

The menus use `...' to indicate that they lead to a dialog box.

There is a new menu item  `Edit | Data editor...'  to edit (via fix())

R objects, especially data frames and matrices.

The console pop-up was checking the wrong item for `Buffered output'.

Plot histories are saved in a different format: those from earlier

versions of R cannot be played back and will be reported as corrupted.

Installing a package now first removes the data and demo directories

if they exist.

Building under (repaired) Cygwin -mno-cygwin environments is no longer

supported.  You probably do need the compiler system recommended for

rw1031 or later.

globalvar.h is no longer used: the header files now declare imported

variables.  This make it essential to use the R header files rather

than copying entries from them.

A bug in some linkers in linking against ATLAS has been circumvented.

There is now a bigger benefit in using ATLAS: on a PII with a

1000x1000 matrix, svd took 288 sec and La.svd 182 sec (without ATLAS)

and 59 sec (with); eigen took 163 sec and La.eigen 53 sec (without)

and 24 sec (with).

rw1031

======

Lines with lty > 1 and many pieces were being drawn very slowly on

Windows 2000 (but not 98/ME).  To work around this, such lines are

now drawn 5000 pieces at a time.

The dialog for the `Change dir' item now uses a standard folder

selection widget for its Browse button.

White backgrounds are now omitted for metafiles (as they are for

postscript, PDF and XFig plots), so white backgounds (the default)

appear to be transparent.

help.start() now updates the HTML search index (as well as the

packages index) when it is started up.  link.html.help() works better

when R_LIBS omits the drive, and uses relative links for the main

library, so R installations can be relocated in the file system.

The background colour of the GUI preferences editor and the

select.list() popup is now taken from the Windows colour scheme.

Rcmd INSTALL now rejects invalid options for --docs (rather than

ignoring them), and checks for the R version in the DESCRIPTION file

exactly the same way as Rcmd check (so with fewer spurious messages).

Added support for building with the ATLAS optimized BLAS library: on a

PII this speeds up La.svd on a 500x500 matrix by about 30%, and the

multiplication of two 1000x1000 matrices by about 8x. See INSTALL.

The recommended compiler system has been changed, but that recommended

for rw1030 still works.

rw1030

======

SetupR.exe and miniR* now include the nine `recommended' packages,

so the miniR* distribution needs six floppies rather than four.

Rgui has a new menu `Packages' with items to load packages, to install

packages from CRAN or from local zip files, and to update packages.

The packages list shown by help.start() now includes all packages in

all libraries, but the search index is still confined to the system

library.

The installers set up a file association for *.RData files, so

double-clicking on a *.RData file launches R in that directory and

loads the *.RData file.  Also, a *.RData file can be dropped onto a

shortcut to Rgui (or Rterm) on the desktop or in Windows Explorer.

Drag-and-drop of images (.RData and .rda) and source files (.R)

onto the Rgui.exe console window is now supported.

Profiling (as described in `Writing R Extensions') is now available.

There is a new `Save as PDF' option on the graphics device menu.

bringToTop() can specify the console window in Rgui (as -1).

The default graphics device is now windows() only in interactive use:

otherwise it is postscript().  (This affects the DCOM interface, which

is not interactive use.)

Support for earlier (pre-Feb 2000) mingw compilers has been dropped:

you must use a compiler system that supports --shared and has an

in-memory dlltool.

Rcmd check has been changed to be more robust to reported problems

with Perl's system() command under 16-bit versions of Windows.  It now

works for us under Windows 98.  (It has always worked under NT4 and

2000.)

Rcmd SHLIB no longer adds a version tab to the DLL, as this seemed to

cause some people problems under Windows 95/98/ME.

The correct file version information should now appear on Windows 2000

Version tab under Properties (working around a Windows 2000 bug).

rwinst.exe is no longer part of the distribution: use the newer

installers to install R, and the Packages menu in Rgui.exe to install

pre-compiled packages, or use an external unzip program.

The old-style Windows help is no longer part of the standard distribution,

but can be made from the sources.  It is no longer tested.

Make targets such as test-Reg have been moved to directory rw1030\tests.

[ DO NOT DO THIS: see ?download.file or rw1040 above:

The default internet module modules\internet.dll is built using basic

WinSock calls.  There is an alternative modules\internet2.dll which uses

WinInet calls (and so needs Internet Explorer installed) which can be

used as a replacement.  (Remove modules\internet.dll and then

rename modules\internet2.dll to modules\internet.dll.)]

rw1023

======

Alternative installers based on Inno Setup 2.0.x, either SetupR.exe or

miniR* (which fits on four floppies).

The location of R_HOME and the version can optionally be recorded in

the Registry (and will be used by the DCOM interface).  The Inno Setup

installers register the installation, and unregister on

uninstallation.  rwinst.exe has an option to register.  Program

rw1023\bin\RSetReg.exe will register, and rw1023\bin\RSetReg.exe /U

will unregister.

The windows() device no longer rounds width and height to the nearest inch.

You can override the settings Windows reports for pixels per inch

(sometimes it is seriously adrift).  See ?windows.

File `extract-usage' needed for codoc was missing from rw1022sp.zip.

The default memory limit (as reset by --max-mem-size) is set to at

least 16Mb, to allow R to start on machines with 8Mb of RAM.

link.html.help() has been re-written using connections and so is

several times faster.

Rcmd INSTALL now allows Windows-style paths to a tar file.

rproxy.dll is now built for StatConnector version 0.99: earlier versions

are no longer supported.

A Windows-specific bug in bitmap() which caused output to appear twice

has been fixed.

Rcmd check now stops when package-specific tests fail (not just

reports on the console).

rw1022

======

The long-running saga of importing R metafiles into Word is over;

lines are now visible in screen previews in Word.  It was necessary to

use `geometric' rather than `cosmetic' pens to achieve scalable line

widths in metafiles: Word was failing to show lines drawn with

`cosmetic' pens.
