 It is true that you sent me the email earlier but the way that my email is sorted, Chuck's emails
were at the top of my list and hence I read it and responded to it first.
With respect to providing me with *all* the info, Chuck did this also although he did so in two
differnt emails. He seems to have CCed only one of them two the r-help mailing list though.
Finally, my follow up question was about something that was mentioned in Chuck's email but was not
in yours.
