MultiCons Consensus Clustering Algorithm

Description

Performs MultiCons clustering, from Al-Najdi et Al. For some reason, if you want to use mclust() clustering, the package needs to be loaded manually

Usage

MultiCons(
  DB,
  Clust_entry = FALSE,
  Clustering_selection = c("kmeans", "pam", "OPTICS", "agghc", "AGNES", "DIANA",
    "MCLUST", "CMeans", "FANNY", "BaggedClust"),
  num_algo = 10,
  maxClust = 10,
  sim.indice = "Jaccard",
  returnAll = FALSE,
  Plot = TRUE,
  verbose = FALSE
)

Arguments

DB	Either data or dataframe of partitions.
Clust_entry	Is DB partitions (TRUE) or data (FALSE).
Clustering_selection	If DB is data, clustering algorithm to select among. Must be included in default value.
num_algo	Number of clustering algorithms to perform.
maxClust	Maximum number of clusters.
sim.indice	Index for defining best partition. Passed to clusterCrit::extCriteria)(), see clusterCrit::getCriteriaNames(FALSE) for other available indexes. If more than one index are given, only the first one will be used.
returnAll	Should all partitions (TRUE) or only the best (FALSE) be returned.
Plot	Should tree be plotted.
verbose	Passed on to mclust() and other functions.

Value

A list of 2: performances and partitions. If returnAll is TRUE, both elements of the list contain results for all levels of the tree, else they only contain the results for the best level of the tree.

Examples

library(mclust)
### With clustering algorithm choices
MultiCons(iris[, 1:4],
          Clustering_selection = c("kmeans", "pam", "DIANA", "MCLUST"),
          Plot = TRUE)
### With a manual clustering entry
parts <- data.frame(factor(rep(c(1,2,3), each = 50)),
                    factor(rep(c(1,2,3), times = c(100, 25, 25))),
                    factor(rep(c(1,2), times = c(50, 100))),
                    factor(rep(c(3, 2, 1), times = c(120, 10, 20))),
                    stringsAsFactors = TRUE)
MultiCons(parts, Clust_entry = TRUE, Plot = TRUE)
