Short overview: The following interpreters are in the PyPy repository
currently (or will be, in the case of Scheme):

 - Python (various people)
 - Prolog (me)
 - JavaScript (Leonardo Santagada)
 - Scheme (Jakub Gustak, not yet started)

In addition, Christopher Armstrong is working on "SafeLisp":

I don't really know either of them very well, but I imagine that the
problem with R would be that you would have to implement all sorts of
numerical functions (which is a lot of effort) or interface to
existing C libraries (which is not much fun, since the rctypes are a
mess, currently).
