ESS provides several features which make it easier to interact with the ESS process (a
connection between your buffer and the statistical package which is waiting for you to input
commands). These include:
• Command-line editing for fixing mistakes in commands before they are entered. The
‘-e’ flag for S-plus provides something similar to this, but here you have the full range
of Emacs commands rather than a limited subset. However, other packages do not
necessarily have features like this built-in. See Section 4.1 [Command-line editing],
page 25.
• Searchable command history for recalling previously-submitted commands. This pro-
vides all the features of the ‘Splus -e’ history mechanism, plus added features such as
history searching. See Section 4.3 [Command History], page 28.
