...g dimensions of the greatest variability in the species data, are restricted to the linear combinations of the environmental variables and the species data. In this way these two sets of data are then directly related." Ref 1: ter Braak, CJF (1986) Canonical correspondence analysis: A new eigenfactor technique for multivariate direct gradient analysis.

Is there an R function that does canonical correspondence analysis. Can it be done using the VR function corresp()? If not, how hard it be to write R code to do it? I am a population biologist with long but patchy programming experience in C, Smalltalk, Java and other languages. Thanks, Patrick Foley patfoley at csus.edu
