Why do people post so much details about their *guesses* on R-help 
rather than looking into the sources or quickly asking the corresponding 
developers?

Anyway, before people start to mention and guess about RWinEdt:
RWinEdt uses the clipboard to transfer code from WinEdt to R, hence any 
Excel data copied to the clipboard will be lost after some code has been 
sent to R.
