I'm afraid your attachment didn't make it into the r-help mail.
Mailing list policy forbids binary attachments other than PS and PDF,
but should be forwarding plaintext attachments, I think.  Perhaps it
requires that the extension be ".txt" or something...?

Anyway... the problem seems diagnosable just from your code:

> WetSeasonMonths <- Cell.ave[Cell.ave$month  >= "5" & Cell.ave$month <=
> "11",]

There is no *string* which is >= "5" and <= "11".  Why aren't you
comparing numerically?
