The optparse package, tested with Rscript but pro
ter solution?
The author of getopt started but did not finish adding positional
arguments to ``getopt``. Howevor, positional arguments have been
supported in the ``optparse`` package for over a year if you specify
``positional_args=TRUE`` to the ``parse_args`` function.

At least in the Unix version of the ``Rscript`` front-end to R (but
oddly enough not ``R CMD BATCH``) you could put something like this in
test.R:
cat("Save workspace image? [y/n]: ")
answer <- tolower( scan("stdin", "", n=1) )
if (substr(answer, 1, 1) == "y") {
q("yes")
} else {
q("no"
If you are using R in a *nix machine then R is usually compiled with
support for gnu-readline which does have a vi mode.
You need a file called ".inputrc" in your home directory containing the
following line:
set editing-mode vi
in order to activate it. It works exactly like the vi

documentation section of the R website:
