View source: R/sim.corrs.R

Description

This function conducts BM simulation on a tree with multiple rates and/or multiple evolutionary correlations between characters. If vcv is a single matrix, instead of a list of matrices, sim.corrs will simulate multivariate BM with a single rate matrix.

Usage

1
sim.corrs(tree, vcv, anc=NULL, internal=FALSE)

Arguments

tree

is a phylogenetic tree in 'phylo' format; or a modified 'phylo' tree with a mapped discrete character.

vcv

is a square covariance matrix or named list of matrices (one for each mapped state on the tree).

anc

optional vector of values for the root state.

internal

logical value indicating whether to return states at internal nodes.

Value

A matrix containing the multivariate tip states for the n species in the tree (and nodes if internal= TRUE).
