\title{Depth and Heights of Nodes and Tips}
\description{
These functions return the depths or heights of nodes and tips.
}
\usage{
node.depth(phy, method = 1)
node.depth.edgelength(phy)
node.height(phy, clado.style = FALSE)
}
\arguments{
\item{phy}{an object of class "phylo".}
\item{method}{an integer value (1 or 2); 1: the node depths are
proportional to the number of tips descending from each node, 2:
they are evenly spaced.}
\item{clado.style}{a logical value; if \code{TRUE}, the node heights
are calculated for a cladogram.}
}
\details{
\code{node.depth} computes the depth of a node depending on the value
of \code{method} (see the option \code{node.depth} in
\code{\link{plot.phylo}}). The value of 1 is given to the tips.
\code{node.depth.edgelength} does the same but using branch lengths.
\code{node.height} computes the heights of nodes and tips as plotted
by a phylogram or a cladogram.
}
\value{
A numeric vector indexed with the node numbers of the matrix `edge' of
\code{phy}.
}
