Oscar,
I'm not quite sure what all these are, but the following may give some of
the things you asked:
## make a reproducible example
library(vegan)
data(varespec)
data(varechem)
mod <- rda(varespec ~ Al + P + K, varechem)
## species--environment correlation
spenvcor(mod)
## "interset" correlation
intersetcor(mod)
## correlations among constraints (why?)
cor(model.frame(mod))
HTH,
Jari Oksanen
