Hi All I am not clear quite how one could use cca from package vegan and the associated predict.cca to predict species abundance from environmental data (or if this is possible in a generalised way). In other words, can one derive a cca object based on known community data and use that to predict e.g. species abundances in a different number of samples based on environmental data? The help notes show that prediction is possible, but it seems that the number of samples is constrained to that in the original, "training" set.
If this is possible, a reference or example would be much, much appreciated.
