\alias{collapseTree}
\title{Interactive tree visualizer}
\usage{
collapseTree(tree, ...)
}
\arguments{
\item{tree}{an object of class \code{"phylo"}.}
\item{...}{optional arguments. These \emph{mostly} match the arguments of \code{\link{plotSimmap}}, but also include the argument \code{drop.extinct=TRUE} which will (if the input tree is ultrametric) drop any 'extinct' lineages from the tree that is returned by the function.}
}
\description{
Function creates an interactive visualization of collapsing & expanding clades on the tree.
}
