Splus Folks,

This must be an elementry problem , but I must be missing the solution.

I would like to conduct a crosstabs analysis of the following "list". I have
tried to follow the example using the solder list in the online help.

crosstabs ( ~ Species + Zone), and several other variations. I have
not been able to figure out how to identify the Ct parameter as the count
data. If someone would be so kind I'd greatly appreciate the pointer.

Thanks Steve F.
