Rstudio plug

For a few years I've been searching for a GUI for the statistics program R. Now I think we have a winner: Rstudio. It doesn't bother providing menu items for graphs or regressions, instead focusing on a great script editor and command line (features like command line syntax highlighting and multiline entry), plus integrated plot, history, variable and help file display. It's really one of the best programming editors I've seen for any language.
