Thanks both, Im happy to have my thoughts confirmed.
Gavin, I ran all of the variables I included through ordisurf aswell as
envfit to see if there were non-linearities, and, in all bar a single case,
the surface isobars happened to be straight. As it turns out, the one that
wasnt linear didnt mak
Hi Alan,
I think that PCA is even better with envfit than NMDS with envfit. This
is because PCA works in linear euclidean world, so correlation makes
better sense in this case. You are correlating points on lines (envfit)
with points on lines (PCA), rather than points on lines (envfit) with
undeter

Hi all,
Im using envfit with some decomposition data currently but with a PCA
result (via vegan:::rda()). Is envfit still valid for PCA results? I guess
it doesnt make so very much difference, just the interpretation is slightly
different.
Or am I barking up the wrong tree by using this approach?
I've removed R-Help from this now...
