Good point, currently I see no way short of directly creating the PDF
file and manually including it in latex, i.e., do

**********************************************************
<<fig=false>>=
pdf(file="foo.pdf", version="1.4")
myplot(...)
dev.off()
@

\incudegraphics{foo}
**********************************************************


But we should think about a more general mechansim to specify defaults
for the PDF device (not only for Sweave).
