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 English.
