Thanks a lot everybody! I see how it works now. But now the other question: I would like to see the Cook's distance plot which is more understandable for me not the Residuals vs Leverage. The one it shows in the examples http://www.personality-project.org/r/r.lm.html But for some reason it doesn't show up.
Thanks a lot.
