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) |
matrix of breeding values/phylogenetic effects
