\name{write.simmap}
\alias{write.simmap}
\title{Write a stochastic character mapped tree to file}
\usage{
write.simmap(tree, file=NULL, append=FALSE, map.order=NULL, quiet=FALSE)
}
\arguments{
\item{tree}{an object of class \code{"simmap"} or \code{"multiSimmap"}.}
\item{file}{an optional filename.}
\item{append}{a logical value indicating whether to append to file.}
\item{map.order}{a optional value specifying whether to write the map in left-to-right or right-to-left order. Acceptable values are "left-to-right" or "right-to-left" or some abbreviation of either. If not provided, \code{write.simmap} will use \code{attr(tree,"map.order")} if available.}
\item{quiet}{logical value indicating whether or not to print a warning message when \code{map.order} is neither specified by a function argument or as an attribute of \code{tree}.}
}
\description{
This function writes stochastic character mapped trees to file using the Newick style format of SIMMAP v1.0 (Bollback 2006).
}
\value{
A file or string (if \code{file=NULL}).
