frag.graph.plot {archeofrag}

Plot a fragmentation graph

Description

A function to plot the graph made by the archeofrag package.

Usage

frag.graph.plot(graph, layer.attr, ...)

Arguments

graph

An igraph undirected object with a "frag_type" attribute.

layer.attr

Character. The name of the vertices attribute giving the layer of each fragment.

...

Optional arguments sent to plot.igraph.

Details

This function is a wrapper for the plot.igraph method for igraph objects. The layout is computed using the fruchterman-reingold algorithm, with some changes as a function of the value of the "frag_type" graph attribute. For graphs including similarity relations, igraph' component_wise layout modifier is applied. For graphs with connection and similarity relationships, the edges for connection relations are coloured in green. For graphs with connection relationships only and two layers, the nodes from the two layers are located based on their layer in the upper and the lower part of the plot.

Value

Returns NULL and plot the graph.
