You can *probably* get this behavior by changing the permissions on  
your R.framework directory. By default, I think it's set to:

drwxrwxr-x  9 root  admin  306 Jun 29 10:39 /Library/Frameworks/ 
R.framework/

Since the RSwitch program monkeys around with which symlinks point to  
what in that folder, you'll need admin rights to use it.

I'm guessing that if you chown or chgrp that directory such that your  
logged in user has the rights to change stuff in there, you can then  
use the app as a non admin .. w/o an app update :-)

HTH,
