Random Generation of MVN Breeding Values and Phylogenetic Effects

Random Generation of MVN Breeding Values and Phylogenetic Effects

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

`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)
