[Rd] [rd] sage <--> r integration

[Mike Hansen]

I would like to re-emphasize the above points that William makes.
Both projects could benefit a lot from working with each other.  A
fair number of people, including Persi Diaconis and Susan Holmes, have
had enthusiastic responses when I mentioned that R was being included
with Sage.

This is a good opportunity to build bridges between the two
communities, and the lack of response (regardless of how GSoC issues
play out) is a bit disappointing.
