R.Version: Version Information

Description

R.Version() provides detailed information about the version of R running.

R.version is a variable (a list) holding this information (and version is a copy of it for S compatibility).

Usage

R.Version() R.version R.version.string version

Arguments

Value

R.Version returns a list with character-string components
platform
the platform for which R was built. A triplet of the form CPU-VENDOR-OS, as determined by the configure script. E.g, "i686-unknown-linux-gnu" or "i386-pc-mingw32".
arch
the architecture (CPU) R was built on/for.
os
the underlying operating system.
system
CPU and OS, separated by a comma.
status
the status of the version (e.g., "alpha")
major
the major version number
minor
the minor version number, including the patchlevel
year
the year the version was released
month
the month the version was released
day
the day the version was released
svn rev
the Subversion revision number, which should be either "unknown" or a single number. (A range of numbers or a number with M or S appended indicates inconsistencies in the sources used to build this version of R.)
language
always "R".
version.string
a character string concatenating some of the info above, useful for plotting, etc.
R.version and version are lists of class "simple.list" which has a print method.

Details

This gives details of the OS under which R was built, not the one under which it is currently running (for which see Sys.info).

Note that OS names might not be what you expect: for example OS X Mavericks 10.9.4 identifies itself as darwin13.3.0, Linux usually as linux-gnu and Solaris 10 as solaris2.10.

Examples

Run this code
require(graphics)

R.version$os # to check how lucky you are ...
plot(0) # any plot
mtext(R.version.string, side = 1, line = 4, adj = 1) # a useful bottom-right note

## a good way to detect OS X:
if(grepl("^darwin", R.version$os)) message("running on OS X")
