PhyloW: Calculates ancestral states of some statistic

Description

Calculates weighted average of covariances matrices along a phylogeny, returning a withing-group covariance matrice for each node.

Usage

PhyloW(tree, tip.data, tip.sample.size = NULL)

Value

list with calculated within-group matrices, using labels or numbers from tree

Arguments

tree

phylogenetic tree

tip.data

list of tip nodes covariance matrices

tip.sample.size

vector of tip nodes sample sizes

Examples

library(ape)
data(dentus)
data(dentus.tree)
tree <- dentus.tree
mat.list <- dlply(dentus, 'species', function(x) cov(x[,1:4]))
sample.sizes <- runif(length(tree$tip.label), 15, 20)
PhyloW(tree, mat.list, sample.sizes)
