[R-SIG-Mac] R does not start on my MacBook Pro3,1

Once toubleshooting a persistent problem with R,
to my embarrassment I found that my "clean install"
was not so clean--  the cause of my troubles lay in my .Rprofile
which I had forgotten about.

Can you be a bit more specific about the error messages you were
getting? (I guess if you can't even start R, it's not likely, but
maybe you remember something about what the error was saying that kept

Also, I'm not sure what version 3,1 means in your MBP description,
which MBP are you runnning? (Though, I doubt it's a problem with the
type of computer)

In the meantime:

* I think the only thing you need to delete in order to clean R out of
your system is:

   * the /Library/Frameworks/R.framework directory
   * /Applications/R.app

   Is that what you cleaned?

* After cleaning and re-install (or now, even), can you run R from the
terminal? Just open up Terminal.app and type "R" (no quotes).
