Internal function for phyl.pca
and others.
lambda.transform(lambda, C)
Typically an among-species phylogenetic variance covariance matrix (e.g., vcv.phylo
) in which the off-diagonal elements have been multiplied by lambda
.
scalar, usually (but not necessarily) on the interval 0,1.
matrix probably returned by vcv.phylo
.
