thank you again.

I have a request for Simon.

On the windows machines, the R and Windows FAQ are both in
c:/Program Files/R/R-2.15.1/doc
Hence I looked for the Mac FAQ in the same place as the R FAQ on Mac.

On windows, searchpaths() gives a list of items like
"c:/Program Files/R/R-2.15.1/library/base"
which gives a starting directory in which to look.

On the Mac, search paths() gives
"/Library/Frameworks/R.framework/Resources/library/base"
which in this case was not helpful for finding the Mac FAQ.

Can you set up a symbolic link from
/Library/Frameworks/R.framework/Versions/2.15/Resources/doc
to point to /Applications/R.app/Contents/Resources?
That will make it easier for the next person converting from windows to mac.

Thanks
Rich
