| R.Version {base} | R Documentation |
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.
R.Version() R.version R.version.string
R.Version returns a list with components
platform |
the platform for which R was built. Under Unix, a
triplet of the form CPU-VENDOR-OS, as determined by the configure
script. E.g, "i586-unknown-linux". |

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.
