Greetings, I have a question pertaining to the concept of "environment variables" that is mentioned in the R documentation for "Startup" and also in the discussion of the Windows configuration of R in the recent book "An Introduction to R" authored by Venables, Smith, and the R Development Core Team (referred to as VS in this message). The Startup documentation and VS make reference to environment variables, e.g., R\_ENVIRON, R_USER, or R\_PROFILE. Apparently the R startup procedure operates differently depending on whether these variables are "set" or "unset". What is unclear to me is how to set these variables. For example, is something to be done with the AUTOEXEC.BAT file or the CONFIG.SYS file, or perhaps one must alter the Properties of the shortcut icon for R? Another possibility is that one must insert some lines in the RProfile file. On my installation I have two files names RProfile. The first is in the directory \rw1041\etc, and the second is in the directory, \rw1041\library\base\R. Does one "set" an environment variable by placing an appropriate line in a RProfile file?

In Win9x and friends it is done in autoexec.bat, but on WinNT,2k,XP you should set it at another place. Details hopefully in the manuals of your OS. 4) You can set it temporarily in R by using Sys.putenv() (that's possible in Rprofile as well, but I think not recommended, just to answer your last question).

You either use the command line or the .Renviron file (just as is documented for Unix). Please upgrade from rw1041 to rw1060 first. -- Brian D.
