Enable Stata-like data manipulation in R.
I wrote genvar, an R package, that introduces an imperative, Stata-like data manipulation/regression syntax to R. The purpose of the project is to make the transition to R friendlier for people coming from fields that predominantly use Stata or other imperative data manipulation environments. By imperative, I mean an environment where a series of commands are executed on a dataset to produce a result.
