• The windows() device would sometimes ignore font family requests (PR#12931).

• The clip region was sometimes wrong when printing from the menu on a windows() graphics device (in 2.7.2 only).

• dir.create(recursive = TRUE) was not working on //server/share paths.

• iconv() was incorrectly identifying R running in an Eastern European locale as using ISO-8859-2 (aka Latin-2) rather than CP1250: they differ in the positions of some characters, notably s and z with caron. This was seen in tcltk output from Rcmdr in 2.7.x, but might have occurred elsewhere (and earlier).

  This also affected localeToCharset() which incorrectly returned "ISO8859-2".

  The same issue seems to have caused problems with starting R 2.7.x in the Chinese (Hong Kong S.A.R.) locale on some systems (e.g. PR#12658).

• Rgui has a new menu item 'Html search page' on the Help menu, which goes directly to the HTML search form. This is needed by users of Firefox 3, which generates incorrect links in search results when the page is accessed via the 'Html help' menu item (or via help.start()).

• Saving a graph in TIFF format could crash R (PR#11804).

• Rterm in interactive use did not implement R_FlushConsole() fully.

• getGraphicsEvent() did not return onMouseMove events while a mouse button was depressed.

• The confirmation of a new frame for a windows() graphics device works harder to give the device focus, including bringing it to the top.

• glob (used by Sys.glob() and unlink()) was not working correctly on some filename patterns including non-ASCII characters. Part of the problem was specific to 2.7.x, part has existed since 2.5.0.

• Sys.glob() returned a UTF-8 result in 2.7.[01] but failed to mark its encoding.

• User menus were not properly removed when a graph window was closed.

• Rscript -e (and Rterm -e) failed on Vista because the MSVCRT function 'tmpfile' is broken on that platform.

• Making a .msi installer now works with WiX 2.0.5805.0 (the file format had been changed since 2.0.4221.0 as previously tested).

• The grid package could set the clipping region outside the device region, and the windows() device now intersects the two when setting the clipping region. Once an invalid region was set, semi-transparent text and lines might have been omitted.

• The Save as | Postscript ... file selection box now offers *.eps (default) and *.ps file selections.

• nchar() now gives the number of characters and their width as would be printed in Rgui for non-representable UTF-8 strings, not as they would be printed in Rterm (via <U+xxxx> escapes).

• savePlot() now adds the file type as an extension to the filename if no dot ('.') is present in the filename. This provides the same default as in versions prior to 2.7.0, but allows the extension to be specified explicitly. (Contributed by Steve Ellison.)

2.7.0 patched BUG FIXES (Windows)

• Sys.getenv() could read incorrectly non-ASCII values.

• Collating (e.g. <) and sorting is done in UTF-8 where one of the items is in UTF-8. It seems that MSVCRT's collation order can be different in widechar and in ASCII, so this can lead to inconsistencies.

2.7.0 OTHERS (Windows)

• The size of the Rgui buffer is now set in characters not bytes (the difference only matters in CJK locales), but for backwards compatibility the entry in Rconsole is still called 'bufbytes'. The default has been increased to 250,000 chars (0.5Mb).

• R CMD now sets TEXINPUTS to .;%R_HOME%/share/texmf;%TEXINPUTS%; by exact analogy with Unix-alikes (that is, including the current directory before R's texmf directory).

• R CMD Rd2dvi defaults to 'yap' as the previewer (rather than xdvi.bat) -- as before this is set by the environment variable 'xdvi'.

• tools::texi2dvi() detects the use of MikTeX's texi2dvi and uses its '-I path' argument to add the path to R's style files (such as Sweave.sty) to the input search path.

• When Sweave() adds its style file, it now uses shortPathName() on the path so that there are no spaces.

• A new menu entry, "Install source package from local folder...", has been added. This uses the R toolset (available as described in Writing R Extensions) to install a package from source.

• install.packages() now handles type="source", repos=NULL installs.

• A new menu entry, "Install source package from local folder...", has been added. This uses the R toolset (available as described in Writing R Extensions) to install a package from source.

• If windows(ypinch=) was specified, the 'width' argument's value was used for the height.

• The Graphapp computation for keyboard accelerators for menus was not always working correctly, at least on Windows XP -- this affected e.g. Alt-M plus 'i' for 'List search path', where 's' was the second 's' was being underlined. (PR#11036)

• Options "graphics.record", "windowsBuffered", "xpinch" and "ypinch" have been replaced by a function windows.options() to set the defaults for the arguments of the windows() device.

• The windows() device has a new argument 'title' to set the title of the window.

• The windows() device no longer sizes the window to allow for scrollbars that might be needed for rescale="fixed", which means the default size really is 7 inches square and not 7.177 inches.

• Saving a graphics window containing semi-transparent colours to BMP, JPEG or PNG now works.

• The bmp(), jpeg() and png() devices support semi-transparent colours. See ?png for use with transparent backgrounds.

  Specifying 'res' to these devices now scales the text size and line width.

• Drawing circles is now done with an integer diameter rather than radius and so can be more accurate for small circles. You can see this in the pairs plot and coplot examples in demo(graphics) which on a 96dpi system use diameter 5 rather than radius 2.

• There is a new tiff() graphics device, and an option to save to TIFF from the graphics device menu and in savePlot(). (The only advantage of (simple) TIFF over PNG is that some journals are unable to cope with formats from as recently as 1996.)

• savePlot() no longer automatically adds an extension to the filename.
