Yes, with the old good cat() and results=tex, you can do anything. It
is just so unnatural. Why must a simple task like setting the size of
a plot involve with so much coding work?

I guess that is not possible with Sweave, but it is possible in the
knitr package (an alternative to Sweave). You can set
opts_knit$set(eval.opts = c('fig.height', 'fig.width'))
so that these two options will be evaluated as R expressions (e.g.
fig.height=x means it takes value from a variable x)
