plotG: Plotting an undirected decomposable graph

Description

The function plots a given undirected decomposable graph.

Usage

plotG(X, vertex_size = 15, vertex_color = "green",
 vertex_frame_color = "green", vertex_label_cex = 1, edge_width = 3)

Arguments

A concentration matrix of v x v dimension.

vertex_size

The size of the vertex, a numeric scalar or vector.

vertex_color

A vector of the node color which should specify a color name or number.

vertex_frame_color

A vector of the node frame color which should specify a color name or number.

vertex_label_cex

A numeric vector of node label size.

edge_width

Edge width.

Value

The output is

an undirected graph

The plotted graph of the given matrix.
