Hi Ricardo, Sweave in LyX 2.0 works a little different. Instead of being relegated to a single document class, it has instead been implemented as a module. The upside is that you can now use Sweave with any document class and with any LaTeX variant (my personal favorite class is the Tufte Handout). This wasn't possible in LyX 1.6 (or, I should say, it was possible but much more difficult).
But before you can use the module, you need to add it to your document. This is done from the Document->Settings->Modules pane. Once the pane is loaded, simply scroll down to Sweave and add it to your dodcument. Then click on "Ok" or "Apply". Once you have done this, a couple of new inset options should appear in the Inset->Custom menu. If you have any problems, go ahead and shoot me an email.
