| NodeOrder {TreeTools} | R Documentation |
Number of edges incident to each node in a tree
Description
NodeOrder() calculates the order of each node: the number of edges
incident to it in a tree.
This value includes the root edge in rooted trees.
Usage
NodeOrder(x, includeAncestor = TRUE, internalOnly = FALSE)
Arguments
x |
A tree of class |
includeAncestor |
Logical specifying whether to count edge leading to ancestral node in calculation of order. |
internalOnly |
Logical specifying whether to restrict to results
to internal nodes, i.e. to omit leaves. Irrelevant if
|
Value
NodeOrder() returns an integer listing the order of each node;
entries are named with the number of each node.
