It’s been a while since R 3.2 was released. Yet, I have been too lazy to update rpy2-py.

rpy2-py is now updated by Derek, along with cran-ggplot2-r, cran-scales-r and cran-rcpp-r.
All the tests are now passed.
See Package Submission for more info.

rpy2-py has python variants, but no r-base variant. It usually point to the latest R.
