widths {phyloTop}

Number of nodes at each depth

Description

Find the number of nodes at each depth in the tree

Usage

widths(tree)

Arguments

tree

a tree of class phylo or phylo4. The tree should be binary and rooted; if not it will be coerced into a binary rooted tree using multi2di, if possible.

Value

A vector of widths, where entry i is the number of nodes at depth i. There is a single node at depth 0 (the root) which is not included in the vector, for simplicity.

Examples

## Find the node widths in a random tree with 10 tips:
tree <- rtree(10)
tree$edge.length <- rep(1,18) # to make it easier to see the width and depths in the plot
plot(tree)
widths(tree)
