treeOfBlobs {MSCquartets}

Tree of blobs for a network

Description

Given extended newick, an evonet object, or an igraph object for a network, return its reduced, unrooted tree of blobs. Here 'reduced' means all nodes resulting from 2-blobs are suppressed, as are edges above the network's LSA.

Usage

treeOfBlobs(net, plot = FALSE)

Arguments

net

A network, supplied as an extended Newick string, an evonet object, or an igraph object

plot

if TRUE (default), plot the tree of blobs.

Value

An object of class phylo containing the unrooted topological tree derived from the network by contracting all blobs. All edge lengths are 1.
