Hi, I'm doing the redundance analysis as a method of ordination between spawning of the species and environmental variables. Anyone know how I can do to get in the summary of the RDA the correlation coefficient among environment variables, species axes and environmental axes results estimates by RDA and the eigenvalues species-environment correlations?.
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
