### Rstat -interpreter and Haskell -interpreters to Sage?

I ~~used mostely ~~use mostly R and python but interested in Haskell. Now I have Sage in iPad, more here, and totally novel idea whether I could get R and Haskell to iPad? I had an impression that Sage is a bunch of different softwares.

Where can I find Sage's dependencies?

Is it possible to run R -code or Haskell -code in Sage?
