SCORE function

community detection method called SCORE Spectral Clustering On Ratios-of-Eigenvectors (SCORE)

SCORE(A, K, threshold = NULL)

Arguments

• A: n-by-n binary symmtric adjacency matrix.
• K: number of communities.
• threshold: (optional) the threshold of ratio matrix. By defalt is log(n).

Returns

A list containing

• R: n-by-(K-1) ratio matrix.
• labels: A vector of integer indicating the cluster to which each point allocated.

Examples

library(igraphdata)
library(igraph)
data('karate')
A = get.adjacency(karate)
karate.out = SCORE(A, 2)
karate.out$labels
