R help - Aug 2009 - : source R-script interactively outside R

DeaR list,

let us assume we have stored a couple of functions in 'test.R'. Is it
possible to run

R CMD BATCH "test.R"
or
R --file="test.R"

interactively and if yes how?

A better formulated question sounds like this: how can I source
"test.R"
interactively OUTSIDE R?

Another clarification try: I want to fix the
"<my-command> in non-interactive use: command-line default will be
used"
Warning Message.

The last one can be reproduced if you type for example:
q("ask")
in "test.R".

I hope at least one of the questions above was formulated understandably.

Thx in advance,
AS

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")
}

Which you would use like this:

Rscript test.R
