Hi
I'd like to know if the R can do the DCCA? Because I can't find the
package about
the DCCA in R. If it can not, please introduce a free software to me, which you
think can easily do the work , thanks!

Hi Jeff
If you tried to search e.g. in Google
detrended canonical correspondence R
would give you some hints
e.g.
decorana {vegan}
R Documentation
Detrended Correspondence Analysis and
Basic Reciprocal Averaging
Cheers

I don't know of any free software to run DCCA. However, you may check Legendre & Casgraine pages at http://www.bio.umontreal.ca/legendre/index.html to prove me wrong. On the other hand, I find it extremely hard to find a reason to find a reason to use detrended CCA. It seems to destroy everything... cheers, jari oksanen -- Jari Oksanen, Oulu, Finland
