If you look through the applied economics journals that require data and code sharing, you'll find that the majority of work is done in Stata. But maybe R is on the rise. It is free, after all.
Thanks to Bob Muenchen and John Ricco. You may also find this translation of Mostly Harmless Econometrics into a few languages useful. Oscar Torres-Reyna's slides are great, too.
