My apologies for sending a binary file. I was following advice from
someone (from this list) who insisted I send data via dput. I guess that
is frown upon.
Anyway. here is a Cellave.txt file.
Stavros, here is the output following your suggestion.
WetMonths <- Cell.ave[Cell.ave$month >= "5" and Cell.ave$month <= "11",]
Error: unexpected symbol in "WetMonths <- Cell.ave[Cell.ave$month >= "5"
and" Cell.ave$month <= "11",]
I think the problem lies in leading characters for months with values 1,
10, 11, and 12. These get very confused.

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?
