Determine the depth of a particular node in a tree, defined as the number of edges between it and the root. (So the root has depth zero, its children have depth one, etc.)
nodeDepth(tree, node)Arguments
- tree
a tree of class
phyloorphylo4. The tree should be binary and rooted; if not it will be coerced into a binary rooted tree using multi2di, if possible.- node
a number corresponding to a node in the tree.
Value
An integer corresponding to the depth of the given node.
Examples
## Find the depth of node 34 in a random tree with 20 tips:
tree <- rtree(20)
plot(tree)
nodelabels()
nodeDepth(tree,34)
