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,)))
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

Science, in constantly seeking real explanations, reveals the true majesty
of our world in all its complexity.
-Richard Dawkins
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.
-Karl Popper
...consider yourself a guest in the home of other creatures as significant
as yourself.
