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.
