DoubleNNI: Double NNI

In TreeSearch: Phylogenetic Analysis with Discrete Character Data

Double NNI

Description

Returns the edge parameter of the two trees consistent with the speficied NNI rearrangement

Usage

DoubleNNI(parent, child, edgeToBreak)

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].
edgeToBreak	In (Rooted/Double)NNI(), an optional integer specifying the index of an edge to rearrange, generated randomly if not specified. If -1, a complete list of all trees one step from the input tree will be returned. In cNNI(), an integer from zero to nEdge(tree) - nTip(tree) - 2, specifying which internal edge to break.

Value

the tree[["edge"]] parameter of the two trees consistent with the specified rearrangement
