Hi Alice,
I can see from your two questions that your English is a bit shaky.
This is not a criticism, I couldn't speak Chinese to save my life. I
looked around for a Chinese R help mailing list and couldn't find one.
Perhaps someone else knows of one. Not only would it make your life
easier at the moment, but it may help you learning R jargon in
