The previous script isn't very good.
I've improved it.
The new version has been tested on Linux and Windows, and with lattice
and ggplot2.
I note that the script is more complex that originally intended.
And I suspect that there maybe (mostly small) problems, that would
require further maintenance.
Running R (by itself) non-REPL with partial interactivity, while it
has merit, may be problematic, in the long run.
(Unless, of course, one were to hack the graphics device(s), but that
would probably be a lot of work).
But in saying that, you're welcome to run R, however, you like.

Usage is similar to before:
> Rscript page.r myfile.r
The file <myfile.r> shouldn't require any modification, can have multiple plots.
Click on the plot, to move to next one...
