motifcluster

An R package for motif-based spectral clustering of weighted directed networks.

Introduction

The motifcluster package provides implementations of motif-based spectral clustering of weighted directed networks in R. These provide the capability for:

• Building motif adjacency matrices
• Sampling random weighted directed networks
• Spectral embedding with motif adjacency matrices
• Motif-based spectral clustering

The methods are all designed to run quickly on large sparse networks, and are easy to install and use. These methods are based on those described in [Underwood, Elliott and Cucuringu, 2020], which is available at arXiv:2004.01293.
