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), whereas R.version.string is a simple character string, useful for plotting, etc.

Usage

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

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, "i586-unknown-linux" 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.

the status of the version (e.g., "Alpha")

major

the major version number

minor

the minor version number, including the patchlevel

year

language

always "R".

R.version and version are lists of class "simple.list" which has a print method.

Note

Do not use R.version$os to test the platform the code is running on: use .Platform$OS.type instead. Slightly different versions of the OS may report different values of R.version$os, as may different versions of R.
