...ivate communication a while back, but in case anyone else cares: I have a version of canonical correspondence analysis (CCA) coded up in R. I based it on Ter Braak and Prentice (1988) Adv. Ecol. Res. 18:271-317, Ter Braak (1986) Ecol. 67(5):1167-1179, and Ter Braak (1995) Section 5.9 in Jongman, Ter Braak, and van Tongeren "Data Analysis in Community and Landscape Ecology". Actually, there are two versions: one which follows Ter Braak's iterative method (slower, but feasible for large problems), the other which directly uses an eigenanalysis (fast, but uses too...

Hi all, I have site data with plant species cover and am looking for trends. I'm kind of new to this, but have done lots of reading and can't find an answer. I tried decorana (I know it's been replaced by ca.) and see a trend, but I'm not sure what it means. Is there a way to get the loadings/eigenvectors of the axes (like in PCA)? Is there a way to do this with rda() too? How

I'm getting lots of grief from reviewers about figures generated with the envfit function in the Vegan package. Has anyone else struggled to effectively explain this analysis? If so, can you share any helpful tips? The most recent comment I've gotten back: "What this shows is which NMDS axis separates the communities, not the relationship between the edaphic factor and the

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
