KeptVerts: Identify vertices retained when leaves are dropped

In TreeTools: Create, Modify and Analyse Phylogenetic Trees

Identify vertices retained when leaves are dropped

Description

Identify vertices retained when leaves are dropped

Usage

KeptVerts(tree, keptTips, tipLabels = TipLabels(tree))

## S3 method for class 'phylo'
KeptVerts(tree, keptTips, tipLabels = TipLabels(tree))

## S3 method for class 'numeric'
KeptVerts(tree, keptTips, tipLabels = TipLabels(tree))

Arguments

tree	Original tree of class phylo, in Preorder.
keptTips	Either: a logical vector stating whether each leaf should be retained, in a sequence corresponding to tree[["tip.label"]]; or a character vector listing the leaf labels to retain; or a numeric vector listing the indices of leaves to retain.
tipLabels	Optional character vector naming the leaves of tree, if keptTips is not logical. Inferred from tree if unspecified.

Examples

master <- BalancedTree(12)
master <- Preorder(master) # Nodes must be listed in Preorder sequence
plot(master)
nodelabels()

allTips <- master[["tip.label"]]
keptTips <- sample(allTips, 8)
plot(KeepTip(master, keptTips))
kept <- KeptVerts(master, allTips %in% keptTips)

map <- which(kept)
# Node `i` in the reduced tree corresponds to node `map[i]` in the original.
