[R] Sweave and \Sexpr{}

[Felipe Carrillo]

Thaks Eric and Dieter:
It is working now although I still have to specify the path to Sweave.sty \usepackage{C:/R/R-2.8.1/share/texmf/Sweave}
and it doesn't evaluate \Sexpr{} when I simply use \usepackage{Sweave}. I placed Sweave.sty in the same folder where my rnw and tex file reside.
