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 macOS Mavericks 10.9.4 identifies itself as darwin13.3.0, Linux usually as linux-gnu and Solaris 10 as solaris2.10.

sessionInfo which provides additional information; getRversion typically used inside R code, .Platform, Sys.info.

Examples

Run this code
# NOT RUN {
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 macOS:
if(grepl("^darwin", R.version$os)) message("running on macOS")
# }
