Thank you all for your help, it looks like www.rseek.org its a good place to look for help.
Hi Felipe, It's a private message, so I hope you don't mind. Regarding your question, personally I think that apropos("what you want here"), i.e, apropos("lm") is very useful. I use www.rseek.org from myy browser and both RSiteSearch("what you want here") and Help+"Html help" (in the tools bar) from the console. Felipe D.
