R.Version {base}

R Documentation

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

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.

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.

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.

R.version.string is a copy of R.version$version.string for simplicity and backwards compatibility.

Examples

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")

## Short R version string, ("space free", useful in file/directory names;
##                          also fine for unreleased versions of R):
shortRversion <- function() {
   rvs <- R.version.string
   if(grepl("devel", (st <- R.version$status)))
       rvs <- sub(paste0(" ",st," "), "-devel_", rvs, fixed=TRUE)
   gsub("[()]", "", gsub(" ", "_", sub(" version ", "-", rvs)))
}
