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

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.

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")
