[ESS] shift-return key binding on ESS Wiki, .R versus .Rnw

[David Afshartous]

All,
There is a nice shift-return key binding described on the ESS Wiki 
(http://www.emacswiki.org/emacs/EmacsSpeaksStatistics#toc3).  I added it 
(shown below) to my .emacs file; it works but only for .R files.  What 
would be the most direct way to change it such that it also works for 
.Rnw files?  (I tried a few things but nothing has worked so far)
Thanks,
David
