Pairwise Distances from a Phylogenetic Network

cophenetic.networx computes the pairwise distances between the pairs of tips from a phylogenetic network using its branch lengths.

Usage

# S3 method for networx
cophenetic(x)

Arguments

x

an object of class networx.

Value

an object of class dist, names are set according to the tip labels (as given by the element tip.label of the argument x).

See also
