Find the number of nodes at each depth in the tree
Usage
widths(tree)
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.
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.
## 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 plotplot(tree)
