This is installation.info, produced by makeinfo version 5.2 from installation.texi. 1. Download the latest zip or tgz archive from ESS downloads area (http://ess.r-project.org/index.php?Section=download) and unpack it into a directory where you would like ESS to reside. We will denote this directory as '/path/to/ESS/' hereafter. Alternatively you can use 'git' to fetch the most recent development version to your local machine with: git clone https://github.com/emacs-ess/ESS.git /path/to/ESS 2. Optionally, compile elisp files and build the documentation with: cd /path/to/ESS/ make Without this step, info, pdf and html documentation and reference card will not be available. 3. Optionally, install into your local machine with 'make install'. You might need administrative privileges: make install The files are installed into '/usr/share/emacs' directory. For this step to run correctly on Mac OS X, you will need to adjust the 'PREFIX' path in 'Makeconf'. The necessary code and instructions are commented in that file. 4. If you have performed the 'make install' step from above, just add (require 'ess-site) to your '~/.emacs' file. Otherwise, you should add '/path/to/ESS/lisp/' to your emacs load path and then load ESS with the following lines in your '~/.emacs': (add-to-list 'load-path "/path/to/ESS/lisp/") (load "ess-site") 5. Restart your Emacs and check that ESS was loaded from a correct location with 'M-x ess-version'. _Note for Windows and Mac OS X users:_ The most straightforward way to install Emacs on your machine is by downloading all-in-one (http://vgoulet.act.ulaval.ca/en/emacs/) Emacs binary by Vincent Goulet. _Note for XEmacs users:_ Due to XEmacs lacking some features that ESS requires, ESS support of XEmacs ends with ESS 12.04-4. This decision will be re-visited in the future as XEmacs continues to sync with GNU Emacs.  Tag Table:  End Tag Table
