net.degree {JGL}

List the degree of every node in all classes.

Description

For each class, lists the degree of every node.

Usage

net.degree(theta)

Arguments

theta

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

Value

degree, a list of p-length vectors, each giving the degree of all p nodes in the network for the corresponding 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 degree list:
net.degree(fgl.results$theta)
