\title{Generates Random Trees}
+\description{
+ These functions generate trees by splitting randomly the edges
+ (\code{rtree}) or randomly clustering the tips (\code{rcoal}).
+ \code{rtree} generates general trees, and \code{rcoal} generates
+ coalescent trees. The algorithms are described in Paradis (2012).

\usage{
rtree(n, rooted = TRUE, tip.label = NULL, br = runif, ...)
rcoal(n, tip.label = NULL, br = "coalescent", ...)
\item{\dots}{further argument(s) to be passed to \code{br}.}
\item{N}{an integer giving the number of trees to generate.}
}
-\description{
- These functions generate trees by splitting randomly the edges
- (\code{rtree}) or randomly clustering the tips (\code{rcoal}).
- \code{rtree} generates general (non-ultrametric) trees, and
- \code{rcoal} generates coalescent (ultrametric) trees.
-}
\details{
The trees generated are bifurcating. If \code{rooted = FALSE} in
(\code{rtree}), the tree is trifurcating at its root.
An object of class \code{"phylo"} or of class \code{"multiPhylo"} in
the case of \code{rmtree}.
