Hi Ali, While you might be interested in using code provided here for preparing lectures for teaching, the purpose of this mailing list is to discuss how to actually teach R in the classroom. Your question is a general question about R not about how to teach R. You really should send these messages to R-help and I note that several other people in the past (besides Gavin) have told you that these posts should be directed at that mailing list and not here as they are off-topic. Also posting to the R-help mailing list will ensure you get a speedy reply. Chris
