louvain: Louvain Community Detection Algorithm

In AlexChristensen/NetworkToolbox: Methods and Measures for Brain, Cognitive, and Psychometric Network Analysis

Louvain Community Detection Algorithm

Description

Computes a vector of communities (community) and a global modularity measure (Q)

Usage

louvain(A, gamma, M0)

Arguments

A	An adjacency matrix of network data
gamma	Defaults to 1. Set to gamma > 1 to detect smaller modules and gamma < 1 for larger modules
M0	Input can be an initial community vector. Defaults to NULL

Value

Returns a list containing:

community	A community vector corresponding to each node's community
Q	Modularity statistic. A measure of how well the communities are compartmentalized
