This blog is updated daily.
A general description is here.
On Windows, the device name for bitmap devices as reported by ‘.Device’ and ‘.Devices’ no longer includes the file name. This is for consistency with other platforms and was requested by the ‘lattice’ maintainer.
‘win.metafile()’ still uses the file name: the exact form is used by package ‘tkrplot’.
‘set.seed(NULL)’ re-initializes ‘.Random.seed’ as done at the beginning of the session if not already set. (Suggestion of Bill Dunlap.)
(‘For experts only’, as the introductory manual says.) The use of environment variables ‘R_NSIZE’ and ‘R_VSIZE’ to control the initial (= minimum) garbade collection trigger for number of cons cels and size of heap has been restored: they can be overridden by the command-line options ‘--min-nsize’ and ‘--min-vsize’; see ‘?Memory’.
File ‘etc/Makeconf’ makes more use of the macros ‘$(CC)’, ‘$(CXX)’, ‘$(F77)’ and ‘$(FC)’, so the compiler in use can be changed by setting just these (and if necessary the corresponding flags) in file ‘~/.R/Makevars’.
This is convenient for those working with binary distributions of R, e.g. on OS X.
The package type ‘"mac.binary"’ now results in a path without Mac subtype (which used to be ‘"universal"’). This is the type used for the CRAN binary distribution for OS X as from R 3.0.0.
