phyl.vcv: Compute evolutionary 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 vcv.phylo.
