unixThe first five fields come from the uname(2) system call. The login name comes from getlogin(2), and the user names from getpwuid(getuid()) and getpwuid(geteuid())

Details

This function is not implemented on all R platforms, and returns NULL when not available. Where possible it is based on POSIX system calls. (Under Windows, it is obtained by Windows system calls and the last three values are the same.)

Sys.info() returns details of the platform R is running on, whereas R.version gives details of the platform R was built on: they may well be different.

See Also

.Platform, and R.version. sessionInfo() gives a synopsis of both your system and the R session.
