\title{Compute all possible resolutions of a node or all nodes in a multifurcating tree}
\usage{
resolveNode(tree,node)
resolveAllNodes(tree)
}
\arguments{
\item{tree}{an object of class \code{"phylo"}.}
\item{node}{for \code{resolveNode}, the node with a polytomy to resolve.}
}
\description{
This functions resolves a single multifurcation or all multifurcations in a tree in all possible ways. If the input tree has edge lengths, then the resolutions will use internal edges of zero length.
}
\details{
For \code{resolveNode} applied to a multifurcation with \emph{n} descendants, the number of resolved trees will be equal to the number of possible rooted trees of \emph{n} taxa. (For instance, three for a trifurcation, 15 for a quadrifurcation, and so on.)
For \code{resolveAllNodes} the number of fully resolved trees will be equal to the product of numbers for \code{resolveNode} applied to each multifurcation separately. (For instance, 45 for a tree containing one trifurcation and one quadrifurcation.)
}
\value{
An object of class \code{"multiPhylo"} - or, if the input tree is already fully resolved, an object of class \code{"phylo"} indentical to \code{tree}.
