Classification Produced By mclust

DESCRIPTION:

Uses the tree$merge component of the output from mclust to determine the classification corresponding to a given number of clusters.

USAGE:

mclass(m, n.clust, aux = NULL) 

REQUIRED ARGUMENTS:

m
the output of mclust, or else an integer vector corresponding to the tree$merge component of the output of mclust.
n.clust
number of clusters.

OPTIONAL ARGUMENTS:

aux
output from a previous call to mclass for a larger number of clusters.

VALUE:

classification
an integer vector in which the kth element identifies the classification of the kth object. Each cluster is identified by its lowest-numbered object. Singletons are numbered 0.
n.clust
number of clusters in the final classification.
mark
an integer vector accumulated as the merge tree is traversed for the purpose of classification.

EXAMPLES:

years <- c("1960", "1964", "1968", "1972", "1976") 
votes.clust <- mclust(votes.repub[,years], method = "S", noise = T) 
# plot the awe on the current graphics device to decide  
# how many groups there are 
plot(x = 1:length(votes.clust$awe), y = votes.clust$awe)   
votes.9 <- mclass(votes.clust, 9) 
votes.3 <- mclass(votes.clust, 3, votes.9)
