< * [[ESSSpeed-bar|speedbar]] -- configure speed bar with ESS.
< To make speedbar show an R buffer's functions, variables, etc, you need to add R to the set of supported extensions; for instance, add to your .emacs
< (speedbar-add-supported-extension ".R")
< By default, speedbar will split the list of functions into groups if there are more than 10. If you do not like this behavior, set the variable speedbar-tag-regroup-maximum-length to a larger number.
< These settings will also work with [[http://www.emacswiki.org/emacs/SrSpeedbar|sr-speedbar]], a mode to make speedbar show in the current frame.

ESS is a package that integrates various statistical software with Emacs. S, R (a free implementation of S), Stata, and SAS modes are all supported by ESS, making it possible to hook writing and programming in Emacs right into your stats. It’s pretty slick.
Consider using the prefix “ESS” for new ESS-related pages. – PaulJohnson

S-<return>’ can launch R and send commands to R (by FelipeCsaszar)
