[Rd] R_PROFILE on Windows

  Dear R-devel,

        There seems to be a bug in the Startup section, regarding the R_PROFILE environment variable in Windows. If not a bug in the Startup itself, perhaps a bug in the documentation.

        According to ?Startup:

       Then R searches for the site-wide startup profile unless the
       command line option '--no-site-file' was given.  The name of this
       file is taken from the value of the 'R_PROFILE' environment
       variable. If this variable is unset, the default is
       '$R_HOME/etc/Rprofile.site'
        
        On Windows XP, I created a batch file with the following lines:

        SET R_PROFILE="C:\fernando\R.profile"
        "C:\progs\R-2.2.0\bin\Rgui.exe"
        
        On c:\fernando\R.profile I had:

        options(foo='bar')

        Running the batch file I created I get, in R:


> options()$foo
NULL
>Sys.getenv("R_PROFILE")
R_PROFILE "\"c:\\fernando\\R.profile\"" I've tried using slashes instead of backslashes
(fernando/R.profile), double blackslashes (fernando\\R.profile) but it seems there's no way to make it work.

        The only way I could manage to have R read the profile was renaming R.profile to .Rprofile and starting R on the directory the .Rprofile was located.

        Is this really the intended behaviour? If so, what's the correct way to specify the R_PROFILE variable and have R use it on Windows?

        Ps: I've tested it on R 2.2.0 and on r-devel r36675, on Windows XP SP2. Sorry if this is a non-bug. I'm a poor linux user trying to survive on Windows, so I might have overloooked something.

        Thank you,
