The Schunk, Sinput, and Soutput environments are defined in Sweave

because it didn't find Sweave.sty, or because it did, but that file has 
been messed up.

Are there really spaces between the backslashes and the macros?  I think 
that doesn't work.  You should also have the \usepackage{Sweave} line 
after the opening \documentclass line.
