ESS also provides for maintaining text versions of your S functions in specified source directories.Statistical packages are powerful software systems for manipulating and analyzing data, but their user interfaces often leave something something to be desired: they offer weak editor functionality and they differ among themselves so markedly that you have to re-learn how to do those things for each package.Meyer and David Smith made further contributions, creating version 3.For version 4, David Smith provided significant enhancements to allow for powerful process interaction. Together with extensions written by Martin Maechler, this became version 4.7 and supported S, Splus, and R.These include: ’ function, for example) severely limiting.
There is an easy to use command history mechanism, including a quick prefix-search history.

ESS corrects these problems by introducing the following features: The ESS environment is built on the open-source projects of many contributors, dating back to 1989 where Doug Bates and Ed Kademan wrote S-mode to edit S and Splus files in GNU Emacs.
