    		CHANGES IN R VERSION 2.12.0
 - 
 
17 
 
 - 
 
18 
 
 - 
 
19 
NEW FEATURES
 - 
 
20 
 
 - 
 
21 
    o	A sub-architecture is used for 32-bit (i386) as well as
 - 
 
22 
	64-bit (x64) builds.  32-bit packages containing compiled code
 - 
 
23 
	need to re-installed for this release (64-bit packages built
 - 
 
24 
	for 2.11.x will most likely still work).
 - 
 
25 
 
 - 
 
26 
	Architecture-specific files (such as Rgui.exe and Rscript.exe)
 - 
 
27 
	are now in R_HOME/bin/i386 or R_HOME/bin/x64.
- 
 
28 
 
 - 
 
29 
	Because many people expect it, there is an executable
 - 
 
30 
	R_HOME/bin/R.exe, which accepts --arch and launches either
 - 
 
31 
	R_HOME/bin/i386/R.exe or R_HOME/bin/x64/R.exe, and analogously
 - 
 
32 
	for Rscript.exe.  If not specified by their argument --arch,
 - 
 
33 
	these check the environment variable R_ARCH for the
 - 
 
34 
	architecture to use.
 - 
 
35
- 
 
36 
    o	The Rgui console now has an optional blinking caret (cursor)
 - 
 
37 
    	to assist screen readers for the visually impaired.
 - 
 
38
- 
 
39 
    o	normalizePath() now signals a warning instead of an error
 - 
 
40 
    	when the input path does not exist.  It attempts partial
 - 
 
41 
    	normalization, or if that fails, returns the original input.
 - 
 
42 
 
 - 
 
43 
    o	All the Rcmd sub-commands except config and Sd2d are now handled
 - 
 
44 
	internally rather by shell scripts.
 - 
 
45 
 
 - 
 
46 
    o	Rcmd has a new command 'texify' to run MiKTeX's texify.exe
 - 
 
47 
	with arguments to find files such as Sweave.sty.  See the
 - 
 
48 
	examples in ?Sweave.
 - 
 
49 
 
 - 
 
50 
 
 - 
 
51 
INSTALLATION
 - 
 
52 
 
 - 
 
53 
    o	The preferred toolchain for 32-bit builds (including packages)
 - 
 
54 
	is now based on gcc 4.5.0: see the 'R Installation and
 - 
 
55 
	Administration Manual'.
 - 
 
56 
 
 - 
 
57 
    o	It is now possible to build R and the standard installer
 - 
 
58 
	 without Perl: only maintainer-mode tasks now need Perl.
 - 
 
59 
 
 - 
 
60 
 
 - 
 
61 
64-bit NEWS
 - 
 
62 
 
 - 
 
63 
    o   The 32- and 64-bit distributions have been merged:
 - 
 
64 
 
 - 
 
65 
    	- There is a combined installer (called R-<version>-win.exe).
 - 
 
66 
	  When used under 32-bit Windows this works as before and
 - 
 
67 
	  installs 32-bit R.  When used under 64-bit Windows there are
 - 
 
68 
	  options to install either or both of 32- and 64-bit R: the
 - 
 
69 
	  current default is to install both.
 - 
 
70 
 
 - 
 
71 
   	- The default package type is "win.binary" on both 32- and
 - 
 
72 
	  64-bit builds: a single repository contains binary packages
 - 
 
73 
	  for both architectures.  This is in place for CRAN and
 - 
 
74 
	  CRANextras: type = "win64.binary" can still be used for
 - 
 
75 
	  repositories which follow the R 2.11.x convention.  With the
 - 
 
76 
	  default filters (see ?available.packages) packages will only
 - 
 
77 
	  be offered if they are available for the current
 - 
 
78 
	  architecture.
 - 
 
79 
 
 - 
 
80 
    o	For those building R from the sources, the 64-bit Tcl binary
 - 
 
81 
	distribution for 2.12.x is in file R64a_Tcl_8-5-8.zip and
 - 
 
82 
	contains e.g. directory Tcl/bin64 and not Tcl/bin.
 - 
 
83 
 
 - 
 
84 
 
 - 
 
85 
PACKAGE INSTALLATION
 - 
 
86 
 
 - 
 
87 
    o	The deprecated environment variable RHOME is no longer set when
 - 
 
88 
	a package is installed: use R_HOME instead (and depend on R
 - 
 
89 
	(>= 2.9) ).
 - 
 
90 
 
 - 
 
91 
    o	Package installation, including 'configure.win' scripts, can
 - 
 
92 
	use ${R_HOME}/bin${R_ARCH_BIN} as a portable way to find
 - 
 
93 
	the binaries such as Rscript.exe.
 - 
 
94 
 
 - 
 
95

 - 
 
109 
BUG FIXES
 - 
 
110 
 
 - 
 
111 
    o	file.rename() now waits for the rename to complete before
- 
 
112 
    	returning, so that operations on the new filename will not fail.
 - 
 
113 
 
 - 
 
114 
    o	Sys.info() and win.version() now report Windows 7 as such (and
 - 
 
115 
	not as Vista), and Sys.info() now reports the machine type as
 - 
 
116 
	'x86-64' on 64-bit platforms.

    		CHANGES IN R VERSION 2.11.1
 - 
 
121 
 
 - 
 
122 
 
 - 
 
123 
NEW FEATURES
 - 
 
124 
 
 - 
 
125 
    o	The Rgui console, pagers and editor on the 64-bit build now have
 - 
 
126 
	a title bar icon.
 - 
 
127 
 
 - 
 
128 
    o	The outer frame/console for Rgui/Rterm mentions '(64-bit)' to
 - 
 
129 
	make it easier to distinguish running copies of R.
 - 
 
130 
 
 - 
 
131 
    o	The package entries in listbox shown by the 'Install package(s)
 - 
 
132 
	...' menu are now explicitly sorted in the current locale
 - 
 
133 
	(there were in most previous releases, but not in 2.11.0).
 - 
 
134 
 
 - 
 
135 
    o	R CMD INSTALL can install zipfiles as binary packages.
 - 
 
136
- 
 
137 
    o	Errors in the Rconsole file are ignored:  silently on startup,
- 
 
138 
    	with a warning when Rconsole is loaded interactively.
 -

    		CHANGES IN R VERSION 2.11.0
 - 
 
143 
 
 - 
 
144 
 
 - 
 
145 
NEW FEATURES
 - 
 
146 
 
 - 
 
147 
    o	There is now a native x64 Windows port, with a binary installer
 - 
 
148 
	and binaries of packages available on CRAN.  See the 'R
 - 
 
149 
	Administration and Installation Manual' and the 'R for Windows FAQ'.
 - 
 
150 
 
 - 
 
151 
    o	'Rcmd cmd' (or 'R CMD cmd') now runs an arbitrary 'cmd' if 'cmd'
 - 
 
152 
	is not one of the builtin commands, and does not have
 - 
 
153 
	extension '.sh' or '.pl' (when it is run as a shell or Perl
 - 
 
154 
	script respectively).  This is done by passing 'cmd' to the
 - 
 
155 
	command interpreter determined by the COMSPEC environment
 - 
 
156 
	variable (which in a vanilla Windows system points to
 - 
 
157 
	cmd.exe).
 - 
 
158 
 
 - 
 
159 
    o	X11() and x11() gain additional arguments to be more similar
 - 
 
160 
	to the Unix X11() device.
 - 
 
161 
 
 - 
 
162 
    o	file.rename() can work across volumes (by copy-and-delete).
 - 
 
163
- 
 
164 
    o	The main HTML help page now links to this CHANGES file.
 - 
 
165 
	(Suggested by Henrik Bengtsson.)
- 
 
166 
 
 - 
 
167 
    o	strftime(format = "%z") now gives the timezone names used by
 - 
 
168 
	the Olson database and not those used by Windows.
 - 
 
169 
 
 - 
 
170 
    o	iconv(to = "ASCII") no longer transliterates, but
 - 
 
171 
	iconv(to = "ASCII//TRANSLIT") will.  This makes
 - 
 
172 
	tools::showNonASCII() work the same way as on other platforms.
 - 
 
173 
 
 - 
 
174 
    o	readRegistry() can look at either the 32- or 64-bit view
 - 
 
175 
	of the Registry on 64-bit Windows.
 - 
 
176 
 
 - 
 
177 
 
 - 
 
178 
INSTALLATION
 - 
 
179 
 
 - 
 
180 
    o	The Tcl timezone files (3Mb on disc) are now an optional part
 - 
 
181 
	of the installation: they would be very rarely used with R.
 - 
 
182 
 
 - 
 
183 
    o	RSetReg.exe has been updated to (un)set the version-specific
 - 
 
184 
	keys in the same way as the main installer, and to have the
 - 
 
185 
	optional argument /Personal to (un)set the per-user rather
 - 
 
186 
	than the per-machine keys (which need administrative access).
 - 
 
187 
 
 - 
 
188 
    o	When building R, the recommended way is now to supply a file
 - 
 
189 
	R_HOME/src/gnuwin32/MkRules.local instead of editing MkRules:
 - 
 
190 
	there is now no MkRules file in the distribution, but one is
 - 
 
191 
	generated during the build process.
 - 
 
192
- 
 
193 
	MkRules.local can be generated by copying and editing
 - 
 
194 
	MkRules.dist.
 - 
 
195 
 
 - 
 
196 
    o	The MSI installer defaults to an all-user (per machine)
 - 
 
197 
	install (by setting the ALLUSERS property to 1).  This can be
 - 
 
198 
	changed at installation, and it can be built for a user-mode
 - 
 
199 
	install (see MkRules.dist).
 - 
 
200 
 
 - 
 
201 
 
 - 
 
202 
BUG FIXES
 - 
 
203 
 
 - 
 
204 
    o	Using ESC to interrupt a system() call could cause R to become
 - 
 
205 
	unstable.
 - 
 
206 
 
 - 
 
207 
    o	0^1i (which should be complex NAN) was incorrect.

		CHANGES IN R VERSION 2.10.1 patched
 - 
 
220 
 
 - 
 
221 
 
 - 
 
222 
BUG FIXES
 - 
 
223 
 
 - 
 
224 
    o	Some of the MDI toolbar buttons (e.g. "Open Script") did not
 - 
 
225 
	return the focus to the console if the user cancelled the
 - 
 
226 
	action.
 - 
 
227
- 
 
228 
    o	system() (and hence shell()) did not set the standard file
 - 
 
229 
    	handles properly, so some programs would not run.
 - 
 
230 
 
 - 
 
231 
    o	setWinProgressBar() did not check the type of its 'title' and
 - 
 
232 
	'label' arguments and might have crashed if they were
 - 
 
233 
	mis-specified.  It now does, thanks to a report by Greg Snow.

239 
 
 - 
 
240 
BUG FIXES
 - 
 
241 
 
 - 
 
242 
    o	The installer did not properly record help type choices in
 - 
 
243 
	R_HOME/etc/Rprofile.site.
 - 
 
244 
 
 - 
 
245 
    o	Rcmd INSTALL once again uses --no-restore, for consistency with
 - 
 
246 
	the Unix version and R 2.9.2.
 - 
 
247
- 
 
248 
    o	The HTML package index was not constructed properly when the
 - 
 
249 
	library path was specified with backslashes.  (Patch submitted
 - 
 
250 
	by Gabor Grothendieck.)

    		CHANGES IN R VERSION 2.10.0
 - 
 
255 
 
 - 
 
256 
 
 - 
 
257 
NEW FEATURES
 - 
 
258 
 
 - 
 
259 
    o	windows() now has a parameter fillOddEven (default TRUE),
 - 
 
260 
	which controls the mode used for polygon fills of self-
 - 
 
261 
	intersecting shapes.
 - 
 
262
- 
 
263 
    o 	The functions arrangeWindows() and getWindowsHandles() have
 - 
 
264 
    	been added to give more programmatic control to the appearance
 - 
 
265 
    	of windows in an R session.
 - 
 
266
- 
 
267 
    o	A Windows menu has been added to the SDI version of the R GUI,
 - 
 
268 
	and the corresponding menu in the MDI version has been
 - 
 
269 
	expanded slightly.
 - 
 
270 
 
 - 
 
271 
    o	The libpng library has been updated to version 1.2.40.
 - 
 
272 
 
 - 
 
273 
    o	The remaining Perl scripts build, check, Rprof, Sd2Rd in
 - 
 
274 
	R_HOME/bin now have extension .pl.
 - 
 
275 
 
 - 
 
276 
    o	Rcmd (or R CMD) can now run .sh (shell) and .pl (Perl) scripts
 - 
 
277 
	anywhere on the path (as well as .bat and .exe files as before).
 - 
 
278 
 
 - 
 
279 
 
 - 
 
280 
PACKAGE INSTALLATION
 - 
 
281 
 
 - 
 
282 
    o	Rcmd SHLIB (which is used by Rcmd INSTALL) now calls 'make'
 - 
 
283 
	without a target, rather than target 'all'.  This is now the
 - 
 
284 
	same as on Unix, and was announced in the NEWS for 2.9.0.
 - 
 
285 
 
 - 
 
286 
    o	Help files are no longer zipped: rendering as text, HTML, latex
 - 
 
287 
	or examples is now done when needed.
 - 
 
288 
 
 - 
 
289 
	Options --use-zip and --use-zip-help in R CMD INSTALL are no
 - 
 
290 
	longer available and --auto-zip only zips data (or not).
 - 
 
291 
 
 - 
 
292 
	Help in packages installed under 2.9.x may not work correctly,
 - 
 
293 
	and a warning is given when such a package is attached by
 - 
 
294 
	library().  Re-installation of all packages is strongly
 - 
 
295 
	recommended (use update.packages(checkBuilt = TRUE)).
 - 
 
296 
 
 - 
 
297 
	Binary packages are installed without CHM help if they contain
 - 
 
298 
	it (as those intended for 2.9.x may).
 - 
 
299 
 
 - 
 
300 
    o	It is possible to install source packages without Rtools
 - 
 
301 
	provided they have no compiled code and no configure.win or
 - 
 
302 
	cleanup.win script.
 - 
 
303 
 
 - 
 
304 
 
 - 
 
305 
INSTALLATION
 - 
 
306 
 
 - 
 
307 
    o	Support for memory profiling is enabled in a standard build
 - 
 
308 
	(this can be changed by editing config.h).
 - 
 
309 
 
 - 
 
310 
    o	CHM help is no longer supported.
 - 
 
311 
 
 - 
 
312 
    o	The help default for the standard installer is HTML help rather
 - 
 
313 
	than CHM help.
 - 
 
314 
 
 - 
 
315 
    o	The categories in the installers have been simplified.  Now the
 - 
 
316 
	files to support installation of source packages are always
 - 
 
317 
	installed (they are now only 0.7Mb), and there are no longer
 - 
 
318 
	categories 'chtml', 'html/help', 'latex' and 'Rd'.
 - 
 
319 
 
 - 
 
320 
 
 - 
 
321 
BUG FIXES
 - 
 
322 
 
 - 
 
323 
    o	'Rcmd open' now works as documented: previously
 - 
 
324 
	'Rcmd open.exe' was required.
 - 
 
325 
 
 - 
 
326 
    o	cat(x, file=) in Rgui tried to interpret UTF-8-encoded strings
 - 
 
327 
	for the console rather than converting them to the native encoding.
 -
