Create a likelihood function for models of simple Brownian
Motion character evolution. This function creates a likelihood
function that can be used in maximum likelihood or
Bayesian inference.
Usage
make.bm(tree, states, meserr=NULL)
Arguments
tree
A phylogenetic tree, in apephylo format.
states
A vector of continuous valued character states. This
vector must be named with the tip labels of tree.
meserr
An optional vector of measurement errors, as standard
deviation around the mean. If a single value is given it is used
for all tips, otherwise the vector must be named as for
states.
Details
This function is heavily based on fitContinuous in the
geiger package. However, this version only fits Brownian
motion models.
