Random Generation of MVN Breeding Values and Phylogenetic Effects

Description

Random Generation of MVN Breeding Values and Phylogenetic Effects

Usage

rbv(pedigree, G, nodes="ALL", scale=TRUE, ggroups=NULL, gmeans=NULL)

Arguments

pedigree	ordered pedigree with 3 columns id, dam and sire or a phylo object.
G	(co)variance matrix
nodes	effects for pedigree/phylogeny nodes to be returned. The default, nodes="ALL" returns effects for all individuals in a pedigree or nodes in a phylogeny (including ancestral nodes). For phylogenies nodes="TIPS" returns effects for the tips only, and for pedigrees a vector of ids can be passed to nodes specifying the subset of individuals for which animal effects are returned.
scale	logical: should a phylogeny (needs to be ultrametric) be scaled to unit length (distance from root to tip)?
ggroups	optional; vector of genetic groups
gmeans	matrix of mean breeding value for genetic groups (rows) by traits (columns)

Value

matrix of breeding values/phylogenetic effects
