I have succesfully (according to testall.py :-) converted RPy to use
numpy instead of Numeric.  Attached patch was tested on Linux only. I
did not attempt to create a package that would support both numpy and
Numeric, but it is easy to do. Please let me know if you are
interested.

For numpy-discussion readers: "RPy is a very simple, yet robust,
Python interface to the R Programming Language."
<http://rpy.sourceforge.net/> 

For rpy-list readers: "Development for Numeric has ceased, and users
should transisition to NumPy as quickly as possible."
<http://numeric.scipy.org/> 

For readers of both lists: Sorry for cross-posting.
