TipsInSplits: Tips contained within splits

Description

TipsInSplits() specifies the number of tips that occur within each bipartition split in a Splits object.

Usage

TipsInSplits(splits, keep.names = TRUE, ...)
# S3 method for Splits
TipsInSplits(splits, keep.names = TRUE, ...)
# S3 method for phylo
TipsInSplits(splits, keep.names = TRUE, ...)
SplitImbalance(splits, keep.names = TRUE, ...)
# S3 method for Splits
SplitImbalance(splits, keep.names = TRUE, ...)
# S3 method for phylo
SplitImbalance(splits, keep.names = TRUE, ...)

Arguments

splits

Object of class Splits or phylo.

keep.names

Logical specifying whether to include the names of splits in the output.

…

Additional parameters to pass to as.Splits().

Value

TipsInSplits() returns a named vector of integers, specifying the number of tips contained within each split in splits.

SplitImbalance() returns a named vector of integers, specifying the number of leaves within a split that are not 'balanced' by a leaf outside it; i.e. a split that divides leaves evenly has an imbalance of zero; one that splits two tips from ten has an imbalance of 10 - 2 = 8.

Examples

# NOT RUN {
tree <- PectinateTree(8)
splits <- as.Splits(tree)
TipsInSplits(splits)

plot(tree)
LabelSplits(tree, as.character(splits), frame = 'none', pos = 3L, cex = 0.7)
LabelSplits(tree, TipsInSplits(splits), unit = ' tips', frame = 'none',
            pos = 1L)
