mstknnclust

mstknnclust implements the MST-kNN clustering algorithm, which determines the number of clusters automatically by recursively intersecting the Minimum Spanning Tree (MST) and k-Nearest Neighbor (kNN) proximity graphs.

Installation

# From CRAN
install.packages("mstknnclust")

# Development version from GitHub
# install.packages("devtools")
devtools::install_github("jorgeklz/package-mstknnclust")

Usage

library(mstknnclust)

# Load the Indo-European languages dataset
data("dslanguages")

# Run clustering (only a distance matrix is needed)
results <- mst.knn(dslanguages)

# Results
results$cnumber   # number of clusters
results$partition # cluster assignments
results$network   # igraph object

# Plot
library(igraph)
plot(results$network,
     vertex.size  = 5,
     vertex.color = components(results$network)$membership,
     layout       = layout_with_fr(results$network, niter = 10000))
