phyl.vcv: Compute phylogenetic VCV matrix for a tree & dataset
Description
Primarily an internal function for phyl.pca; this can be used to compute the phylogenetic trait variance-covariance matrix given a phylogenetic VCV, lambda, and a data matrix.
Usage
phyl.vcv(X,C,lambda)
Arguments
lambda
value for lambda transformation.
X
data matrix.
C
matrix containing the height above the root of each pair of species in the tree. Typically this will have been produced by calling {link{vcv.phylo}.
