Hi,
In 'example(barplot)' running in R, I see 'Hit <Return> to see next
plot:', then R waits for my input. I am wondering how to wait for a
user response in Rscript.
Rscript doesn't run R interactively, so I doubt if there's a way to do
this. Rterm has the --ess option that asserts interactive use when
reading piped input, so you might be able to do something like
Rterm --ess <script.R
but that's not the intended use, so you may find other problems.
If you want interactive use but don't want the full Rterm or Rgui, you
really should be writing your own front-end. It's not trivial, but it's
not impossible either, and there are samples included with the R sources.
