You shouldn't need Sweave.sty in your local directory for this to work.  
You aren't changing it,
just using one of its options.

There are other ways to control the size:  it isn't always 80%.  I 
normally use something like
\setkeys{Gin}{width=0.75\textwidth} to control it.  You can reset this a 
number of times in
the same document.  (Read the LaTeX docs for graphicx to see the other 
keys that can be set.)
