graph.pattern: Graph Pattern Visualization

In Tlasso: Non-Convex Optimization and Statistical Inference for Sparse Tensor Graphical Models

Description

Draw an undirected graph based on presicion matrix to present connection among variables.

Usage

graph.pattern(
  mat,
  main = NULL,
  edge.color = "gray50",
  vertex.color = "red",
  vertex.size = 3,
  vertex.label = NA,
  thres = 1e-05
)

Arguments

mat	precision matrix that encodes information of graph struture.
main	main title of graph. Default is NULL.
edge.color	color of edge. Default is "gray50".
vertex.color	color of vertex. Default is "red".
vertex.size	size of vertex. Default is 3.
vertex.label	label of vertex. Default is NA.
thres	thresholding level of substituting entry with zero, set entry to zero if its absolute value equals or is less than thres. If thres is negative or zero, no entry will be substituted with zero.

Details

This function generates an udirected graph based on precision matrix. If an entry is zero, then no edge connects corresponding pair of nodes.

Value

A plot of undirected graph.
