Why do you need to call trellis.par.get? I don't see you using 'sup'
(maybe in the ... part), and I don't see why you would need to.

An Rplots.ps may still be produced by Sweave (I forget the reason, but
something to do with the need for an explicit print), but shouldn't
happen when running the R code separately.
