Constrained ordination

Canonical Correspondence Analysis (CCA)

Theory

Constrained ordination method based on correspondence analysis. Adjusted R2 cannot be calculated for CCA - although there exist a bootstrap method for it, this is still not implemented in R 1), so only ordinary R2 can be calculated.

1)
check the paper from Peres-Neto et al. (2006), where is an executable program VarCan, based on Matlab, calculating adjusted R2 in CCA - it's in Supplement 3 available online; newly, since version 5.04, permutation-based adjusted R2 can be calculated using Canoco 5, see update information, Improvement [504-23]
