cluster_pam: PAM (Partitioning Around Medoids)

Description

Clustering around representative data points (medoids) using cluster::pam.

Usage

cluster_pam(k = 1)

Value

returns PAM object.

Arguments

k

the number of clusters to generate.

Details

More robust to outliers than k‑means. The intrinsic metric reported is the within‑cluster SSE to medoids.

Examples

# setup clustering
model <- cluster_pam(k = 3)

#load dataset
data(iris)

# build model
model <- fit(model, iris[,1:4])
clu <- cluster(model, iris[,1:4])
table(clu)

# evaluate model using external metric
eval <- evaluate(model, clu, iris$Species)
