net.edges {JGL}

List the edges in a network

Description

For each class, list every pair of connected nodes.

Usage

net.edges(theta)

Arguments

theta

A list of pXp matrices, each an estimated sparse inverse covariance matrix. (For example, the result of FGL or GGL.)

Value

edges, a K-length list, each element of the list an igraph.es object detailing all pairs of connected nodes in the class.

Examples

## load an example dataset with K=two classes, p=200 features, and n=100 samples per class:
data(example.data)
str(example.data)
## run fgl:
fgl.results = JGL(Y=example.data,penalty="fused",lambda1=.25,lambda2=.1)
## get edges list:
net.edges(fgl.results$theta)
