Yes, that looks fine.  So the problem is likely with pdflatex, or maybe 
you haven't really solved the Sweave.sty problem yet.
Do you run pdflatex locally, or do you try to run it from a different 
directory?  I doubt if that would work, because the path to the
images would be wrong.

Do you have a file called demo-FigureExample.pdf after running Sweave, 
and does pdflatex produce a demo.log file containing something like this:

<demo-FigureExample.pdf, id=1, 433.62pt x 433.62pt>
File: demo-FigureExample.pdf Graphic file (type pdf)

<use demo-FigureExample.pdf> [1

{C:/Users/murdoch/AppData/Local/MiKTeX/2.8/pdftex/config/pdftex.map}] [2 
<C:/te
mp/demo-FigureExample.pdf>]

or does it contain some errors?
