I think it's too late for that one. keep.source was introduced in 2006,
and there were a large number of unreasonable complaints about it -- so
many that I'm not going near that again.

Why do you want to keep Rplots.pdf? I think a more reasonable request
is not to produce it at all.

I think this is an option. Use something like
\usepackage[nogin]{Sweave}
to turn it off.

That's a good idea that has been suggested before. I think it's just a
matter of someone doing it (or it may have been done in one of the
Sweave add-on packages).> Furthermore, any help appreciated here:

I think the generic answer here is that you shouldn't be using an OS
where starting new instances is so time consuming. Make is designed for
OS's where it's rather cheap to start the same program many times. So
maybe you should suggest to Microsoft (I'm assuming you're on Windows)
about that fact that it is so slow at this common task?

Besides the one above, you can use \setkeys{Gin} to change the default
size of graphics.> Furthermore, I'm temped to stop Sweave from generating all the eps

I think this depends on your audience, but probably most users of a
document written using Sweave are just going to read the PDF that you
produced, they aren't going to process it themselves. On the other
hand, those eps files are handy because they allow you to work with .dvi
files, and .dvi previewers are still smarter than .pdf previewers, for
things like reverse search. (Use patchDVI so reverse searches go to the
.Rnw file, not the intermediate .tex file.) So I leave Sweave producing
both pdf and eps. Disk space is cheap.
