edge_to_splits {TreeTools}

Efficiently convert edge matrix to splits

Description

Wrapper for internal C++ function for maximum efficiency. Improper input may crash R. Behaviour not guaranteed. It is advisable to contact the package maintainers before relying on this function.

Usage

edge_to_splits(
  edge,
  edgeOrder,
  tipLabels = NULL,
  asSplits = TRUE,
  nTip = NTip(edge),
  ...
)

Arguments

edge

A matrix with two columns, with each row listing the parent and child node of an edge in a phylogenetic tree. Property edge of objects of class phylo.

edgeOrder

Integer vector such that edge[edgeOrder, ] returns a postorder ordering of edges.

tipLabels

Character vector specifying sequence in which to order tip labels. Label order must (currently) match to combine or compare separate Splits objects.

asSplits

Logical specifying whether to return a Splits object, or an unannotated two-dimensional array (useful where performance is paramount).

nTip

Integer specifying number of leaves in tree.

...

Presently unused.

Value

edge_to_splits() uses the same return format as as.Splits().
