Hybrid Trait Evolution under Brownian Motion

Analyzes the phenotypic evolution of species of hybrid origin on a phylogenetic network. This package can detect the hybrid vigor effect, a burst of variation at formation, and the relative portion of heritability from its parents. Parameters are estimated by maximum likelihood. Users need to enter a comparative data set, a phylogeny, and information on gene flow leading to hybrids. See Jhwueng and O'Meara (2017) .


Build Status

This is a package for doing comparative methods on networks. It's been in peer review twice but not accepted, and the current version has a fatal flaw. So don't use it.

To install it (but see caveat above):

install.packages("BMhyb")
devtools::install_github("bomeara/BMhyb")
