Compute silhouette statistics for cluster validation
Usage
tidy_silhouette(clusters, dist_mat)
Arguments
- clusters
Vector of cluster assignments
- dist_mat
Distance matrix (dist object)
Value
A list of class "tidy_silhouette" containing:
silhouette_data: tibble with silhouette values for each observation
avg_width: average silhouette width
cluster_avg: average silhouette width by cluster
Examples
# \donttest{
km <- kmeans(iris[, 1:4], centers = 3, nstart = 25)
d <- dist(iris[, 1:4])
sil <- tidy_silhouette(km$cluster, d)
# }
