I guess that R has a search path with both locations?

/usr/share is the right place for noarch libraries.

We shouldn't.

We shouldn't either. 

If the user mixes rpm installed and hand installed softwares he should
know what he is doing, doing things automatically is not right when we
don't know the user intentions.

Now maybe there could be some facilities in R in fedora to help user 
install his stuff in a specific path (for example /usr/local/lib or 
/usr/local/share) in order not to install stuff in directories that are 
traditionnally under rpm conrol, like /usr/lib and /usr/share. But I
don't know if it is feasible, nor easy, and I am not sure that it is
desirable either.
