The Sweave manual (section 4.1.2 in my version) suggests using something like this before the figure call:


This sets the size globally. Not perfect, but it's what I've been doing. I would myself like the ability to add optional arguments to the produced \includegraphics call, but perhaps there is a good reason why this hasn't been implemented (other than that the developer might not have thought it useful/necessary, which is in itself a perfectly good reason why this feature is not there).

I haven't tried it, but perhaps if you have a named figure code chunk, this name is used for the file name?
