Sweave runs figure chunks multiple times.  The first time is probably 
what you're seeing:  it just runs the code, with no special devices 
created.  You need to tell R to use something other than your screen as 
the default device for this.  That's what happens if you run Sweave in 
batch mode, or if you choose options(device="pdf").  (You'll get a file 
Rplots.pdf created.)
