Dear all,

I'm studying sexual dimorphism of individuals of three populations of a
lizard species. One of my goals is to evaluate if shape variables differ for
males and females, both within and among populations.

To eliminate size effect upon shape variables I want to use CPCA with
back-projection (as pointed by McCoy et al., 2006 Oecologia 148:547-554)
method for this analysis. After some efforts I have installed the package
cpcbp (http://www.math.mcmaster.ca/~bolker/R/src/contrib/cpcbp_0.3.2.tar.gz)
in R.

However, It seems that cpcbp is not able to deal with a two way problem...
examples given in the documentation of the package were always for one
categorical variable. And bp.anova() seems to only perform an one way-ANOVA.
That's where my troubles are.

Since I have two factors (sexes and localities) I'm in need of advices to
handle with the CPCA/BBPM to evaluate my objective.

I thank you in advance,
Sincerely,
Conrado
