sim.corrs | R Documentation |
Simulates multivariate Brownian motion evolution on a tree with multiple evolutionary correlation/covariance matrices.
sim.corrs(tree, vcv, anc=NULL, internal=FALSE)
tree |
an object of class |
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. |
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.
A matrix containing the multivariate tip states for the n
species in the tree (and nodes if internal=
TRUE
).
