TreeTools (version 1.9.2)

NonDuplicateRoot: Non-duplicate root

Description

Identify, for each edge, whether it denotes a different partition from the root edge. The first edge of the input tree must be a root edge; this can be accomplished using Preorder().

Usage

NonDuplicateRoot(parent, child, nEdge = length(parent))

Value

NonDuplicateRoot() returns a logical vector of length nEdge, specifying TRUE unless an edge identifies the same partition as the root edge.

Arguments

parent

Integer vector corresponding to the first column of the edge matrix of a tree of class phylo, i.e. tree[["edge"]][, 1]

child

Integer vector corresponding to the second column of the edge matrix of a tree of class phylo, i.e. tree[["edge"]][, 2].

nEdge

(optional) integer specifying the number of edges of a tree of class phylo, i.e. dim(tree[["edge"]])[1]
