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

TipsInSplits(splits, keep.names = TRUE, smallest = FALSE, ...)

# S3 method for Splits
TipsInSplits(splits, keep.names = TRUE, smallest = FALSE, ...)

# S3 method for phylo
TipsInSplits(splits, keep.names = TRUE, smallest = FALSE, ...)

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.

smallest

Logical; if TRUE, return the number of leaves in the smaller bipartition.

...

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.
