\name{di2multi.simmap}
\alias{di2multi.simmap}
\title{Collapse branches of zero length to polytomy in stochastic map style tree}
\usage{
\method{di2multi}{simmap}(phy, ...)
}
\arguments{
\item{phy}{object of class \code{"simmap"} containing a stochastically mapped discrete character.}
\item{...}{optional argument \code{tol}, length below which edges should be treated as having zero length.}
}
\description{
This function collapses branches of zero length (or, more specifically, branches with length shorter than \code{tol}) to create a polytomy in a stochastic-map style tree.
}
\details{
This function should theoretically perform similarly to \code{\link{di2multi}} in ape.
}
\value{
A tree with a stochastically mapped discrete character
