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! jeff
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 Petr On 4 Jan 2005 at 12:13, ys03165003 at student.ecnu.edu.c wrote:> Hi > > I'd like to know if the R can do the DCCA?

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
