You are right (ideally), but this is a long-lasting annoying problem with R's default graphical device which is pdf() in the non-interactive session. Unfortunately it has to create a file under the current working directory (usually named Rplots.pdf). I requested a true null device which does not write files, and it was implemented in R 2.14.1, but again, unfortunately it has a bug which makes this null device still write a file named NA. I have not got any response from R core yet about this bug.
I can submit a simple patch to lyxsweave.R to avoid this problem by redirecting the default file to a temp dir, but I'm not sure if it is still in time. It should not break string freeze, though.
