Greetings
Using the following command I've been trying to subset a
dataframe of
counts of an organism to compute the sizes of groups for use as a
predictor:
Hs.patches <- as.data.frame(with(Hs.long,
table(Cave,Year,Month,Region,Plot,)))
Not really sure what you intended. Did you want a contingency table in
long format or a subset:
If the first, then perhaps:
Hs.patches <-with(Hs.long, as.data.frame(
table(Cave,Year,Month,Region,Plot,)))
(There is also an equivalent as.data.frame.table function.)

I am getting the following error message that I do not understand:
ERROR: argument is missing, with no default
Can anyone shed light on this and suggest a possible fix?
Cheers
Kurt

The scientific tradition is distinguished from the pre-scientific
tradition
in having two layers. Like the latter it passes on its theories but
it
also passes on a critical attitude towards them. The theories are
passed
on not as dogmas but rather with the challenge to discuss them and
improve
upon them.
