[R] : source R-script interactively outside R

[Trevor Davis]

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
