node.depth {ape} | R Documentation

## 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

`phy` | an object of class "phylo".
`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.
`clado.style` | a logical value; if `TRUE`, the node heights are calculated for a cladogram.

### Details

`node.depth` computes the depth of a node depending on the value of `method` (see the option `node.depth` in `plot.phylo`). The value of 1 is given to the tips.

`node.depth.edgelength` does the same but using branch lengths.

`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 `phy`.
