+1.

R has considerable infrastructure to support litterarate programming,
and it makes little sense to avoid using it because a) some
hypothetical users will have difficulty installing the software or b)
because other languages supported by babel lack similar functionality.
We are currently missing out on some useful things available in other
literate programming systems for R, such as the ability to easily
return interleaved input and output, and I would really like to see R
support in babel take advantage of existing R features to provide a
first-class R literate programming environment.
