as.networx: Conversion among phylogenetic network objects

Description

as.networx convert splits objects into a networx object. And most important there exists a generic plot function to plot phylogenetic network or split graphs.

Usage

as.networx(x, ...)
# S3 method for splits
as.networx(x, planar = FALSE, coord = "none", ...)
# S3 method for phylo
as.networx(x, ...)

Arguments

x

an object of class "splits" or "phylo"

...

Further arguments passed to or from other methods.

planar

logical whether to produce a planar graph from only cyclic splits (may excludes splits).

coord

add coordinates of the nodes, allows to reproduce the plot.

Details

A networx object hold the information for a phylogenetic network and extends the phylo object. Therefore some generic function for phylo objects will also work for networx objects. The argument planar = TRUE will create a planar split graph based on a cyclic ordering. These objects can be nicely plotted in "2D".
