Sorry for the lack of precision. Sweave worked perfectly within R. It  
is when I tried to compile the ".tex" document with LaTeX (via  
TeXShop) that i got the error message.

I don't know if my system is case-insensitive (Mac OS X 10.5.5), I  
think it is. More importantly, I wrote the error message wrong. I just  
checked and Sweave was capilalized.

I should have been clearer that Sweave worked well within R, and that  
it was my LaTeX installation could not find Sweave.sty. In fact I  
hesitated between asking the Mac-LaTeX  list or the Mac-R list, and  
decided upon the later because I felt more readers of this list use  
both R and LaTeX.

I guess my question becomes: why do I get this message from LaTeX that  
I did not get when I was using R 2.7 instead of 2.8, TeXLive 2007  
instead of 2008.

For now, I can keep working by placing a copy of Sweave.sty in the  
directory where both my ".Rnw" and ".tex" files reside.
