Quartet (version 1.2.6)

CompareQuartets: Compare quartet states by explicit enumeration

Description

CompareQuartets() uses explicit enumeration to compare two lists of quartet states, detailing how many are identical and how many are unresolved. For most purposes, the faster function QuartetStatus() will be preferable.

Usage

CompareQuartets(x, cf)

Value

Returns an array of seven numeric elements, corresponding

N

The total number of quartet statements for two trees of n leaves, i.e. 2 Q.

Q

The total number of quartets for n leaves.

s

The number of quartets that are resolved identically in both trees.

d

The number of quartets that are resolved differently in each tree.

r1

The number of quartets that are resolved in tree 1, but not in tree 2.

r2

The number of quartets that are resolved in tree 2, but not in tree 1.

u

The number of quartets that are unresolved in both trees.

Arguments

x, cf

List of quartet states, perhaps generated by QuartetStates().
