[R-sig-eco] Co-correspondence analysis

[Duarte Viana]

Dear all,

I want relate two matrices of species presence-absence data,
preferably in a predictive manner. Is it reasonable to do it by
co-correspondence analysis using the "coca" function in the
"cocorresp" package? Some papers seem to use presence-absence data,
but the help document for this function only refers to abundance data.

Any insights in this would be greatly appreciated.
