plot.cglasso2igraph {cglasso}

Plot Method for a cglasso2igraph Object"

Description

plot.cglasso2igraph produces graphs from an R object of class ‘cglasso2igraph’.

Usage

## S3 method for class 'cglasso2igraph'
plot(x, type, ...)

Arguments

x

an R object of class ‘cglasso2igraph’, that is, the output of the function to_graph.

type

a description of the required graph. Default is ‘both’ in a conditional glasso estimator or ‘Gyy’ in a glasso estimator (see getGraph).

...

additional graphical arguments passed to the functions plot.igraph.
