As far as I know, there is no function in R to run detrended 
constrained correspondence analysis (if 'DCCA' is an acronym for that 
method). 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...
