R help - Jan 2008 - R and Vista

Hello R users,
I have been using R for a while on xp and have just updated my system to
vista. Have encountered some problems... First and main problem is that i
cannot make R recognize my own written functions by coping them into the
Rprofile.site on the etc folder. For some reason, this very useful tool
seems not to be working anymore. Could someone help?? Any other suggestion
to make R start with my functions?
Thanks a lot,
Marcia

What does the command

R.home()

print in an R session on your system? Can you add "/etc/Rprofile.site"
to the end, and read the file?  For example, on my system I see

 > R.home()
[1] "F:\\R\\R-2.6.1"

and see

 > readLines("F:\\R\\R-2.6.1/etc/Rprofile.site")
  [1] "# Things you might want to change" 

  [2] "" 

  [3] "# options(papersize=\"a4\")" 

  [4] "# options(editor=\"notepad\")"

The error is about the single backslashes (I used forward slashes, 
because that's what R uses internally), and the lack of quotes.  You 
should try

readLines("C:\\PROGRA~2\\R\\R-25~1.0/etc/Rprofile.site")

However, I'm guessing based on your path that you're using R 2.5.x. 
I'd
upgrade to 2.6.1 if you can; it has had some things fixed to deal with 
Vista.
