\name{minSplit}
\alias{minSplit}
\title{Finding the minimum (median) split in the posterior sample}
\usage{
minSplit(tree, split.list, method="sum", printD=FALSE)
}
\arguments{
\item{tree}{a phylogeny stored as an object of class \code{"phylo"}.}
\item{split.list}{either a matrix with two named columns, \code{"node"} and \code{"bp"}; a \code{$mcmc} matrix from \code{evol.rate.mcmc()}; or the entire raw output from \code{evol.rate.mcmc()}.}
\item{method}{an optional string indicating the criterion to minimize: options are \code{"sum"} and \code{"sumsq"}.}
\item{printD}{logical specifying whether to print distances to screen (\code{FALSE} by default).}
}
\description{
This function takes a phylogenetic tree and a list of splits and identifies the split with the smallest summed or summed squared distances to all the other splits. Used to be called \code{min.split()} but was changed to avoid conflict with the generic \code{\link{min}}.
}
\value{
A list with the following components:
\item{node}{node for the minimum split.}
\item{bp}{location on the branch leading to \code{node} of the minimum split.}
}
