n_clusters

Number of clusters to extract

Description

This function runs many existing procedures for determining how many clusters are present in data. It returns the number of clusters based on the maximum consensus. In case of ties, it will select the solution with fewer clusters.

Usage

n_clusters(
  x,
  standardize = TRUE,
  force = FALSE,
  package = c("NbClust", "mclust", "cluster", "M3C"),
  fast = TRUE,
  ...
)

Arguments

`x`	A data frame.
`standardize`	Standardize the dataframe before clustering (default).
`force`	Logical, if `TRUE`, factors are converted to numerical values in order to be included in the data for determining the number of clusters. By default, factors are removed, because most methods that determine the number of clusters need numeric input only.
`package`	Package from which methods are to be called to determine the number of clusters. Can be `"all"` or a vector containing `"NbClust"`, `"mclust"`, `"cluster"` and `"M3C"`.
`fast`	If `FALSE`, will compute 4 more indices (sets `index = "allong"` in `NbClust`). This has been deactivated by default as it is computationally heavy.
`...`	Arguments passed to or from other methods.

Note

There is also a plot()-method implemented in the see-package.

Examples

library(parameters)

if (require("mclust", quietly = TRUE) && require("NbClust", quietly = TRUE) &&
  require("cluster", quietly = TRUE)) {
  n_clusters(iris[, 1:4], package = c("NbClust", "mclust", "cluster"))
}
