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
phyloobject.- 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 phylogeniesnodes="TIPS"returns effects for the tips only, and for pedigrees a vector of ids can be passed tonodesspecifying 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
