Using CLI software, an infrequent user has trouble

older).  What might help is an added help facility more 
oriented towards
tasks, rather than structured around functions or packages.

Another good (non-GUI) tool for the CLI is keyword 
completion.  R in ESS
does this, giving you lists of possible functions, variables 
and objects,
or feedback if there isn't any.  R's CLI completes, but only with
filenames in the current directory.
That works only if R was compiled with readline.  Thus it doesn't work that
way on Windows, for example.  Completion still works on Windows under ESS
though.
