I thought I'd install Sweave but it's not happy at the moment. I followed the instructions in the wiki and those that Jeff Laake wrote for Vista but without any luck.
When trying out the Norma-01.lyx file I get the error message seen here http://www.mediafire.com/?clprb8qpw2e242v . I've tried both both Rweave.bat suggestions that Jeff mentioned. I'm a Tinn-R user so I added "-n0-site-file" in both cases. Any suggestions?
