fitThresh {phytools}

Fits multi-state threshold model using the discrete approximation

Description

This function uses the discrete approximation of Boucher and Demery (2016) to fit a multi-state discrete character threshold model following Felsenstein (2012; Revell 2014).

Usage

fitThresh(tree, x, sequence=NULL, ...)

Arguments

tree

object of class "phylo".

x

a named vector.

sequence

assumed ordering of the discrete character state. If not supplied and then alphanumeric order is assumed.

...

optional arguments.

Value

An object of class "fitThresh".
