Clustering evaluation through stability

Description

Evaluation a clustering algorithm according to stability, through a bootstrap procedure.

Usage

stability(
  clusteringmethods,
  d,
  originals = NULL,
  eval = "jaccard",
  type = c("cluster", "global"),
  nsampling = 10,
  seed = NULL,
  names = NULL,
  graph = FALSE,
  ...
)

Arguments

clusteringmethods	The clustering methods to be evaluated.
d	The dataset.
originals	The original clustering.
eval	The evaluation criteria.
type	The comparison method.
nsampling	The number of bootstrap runs.
seed	A specified seed for random number generation (useful for testing different method with the same bootstap samplings).
names	Method names.
graph	Indicates wether or not a graphic is potted for each sample.
...	Parameters to be passed to the clustering algorithms.

Value

The evaluation of the clustering algorithm(s) (numeric values).
