What is ESS?

Welcome to the home page of the ESS project

Emacs Speaks Statistics (ESS) is an add-on package for GNU Emacs. It is designed to support editing of scripts and interaction with statistical analysis programs: mainly R and SAS. All are welcome to try ESS for free. But advanced users who regularly work with statistical analysis scripts will likely benefit from it the most.

The rationale for developing ESS is that most statistical analysis systems provide a more or less sophisticated graphical user interface (GUI). However, their full power is only available using their scripting language. Furthermore, complex statistical analysis projects require a high degree of automation and documentation which can only be handled by creating statistical analysis scripts. Unfortunately, many statistics packages provide only weak text editor functionality and show major differences between them. Without a unified text editor user interface additional effort is required from the user to cope with limited functionality and with text editor differences.

Therefore, emacs editors and the ESS package provide the following major features: ESS is freely available under the GNU General Public License (GPL). For further technical and legal information please refer to the ESS Manual (cf. section Documentation).
