Plot combined clusterings results: classifications corresponding to Mclust/BIC and to the hierarchically combined classes, "entropy plots" to help to select a number of classes, and the tree structure obtained from combining mixture components.

# S3 method for clustCombi
plot(x, what = c("classification", "entropy", "tree"), ...)

Arguments

x

Object returned by clustCombi function.

what

Type of plot.

...

Other arguments to be passed to other functions: combiPlot, entPlot, combiTree. Please see the corresponding documentations.

Value

Classifications are plotted with combiPlot, which relies on the Mclust plot functions. Entropy plots are plotted with entPlot and may help to select a number of classes: please see the article cited in the references. Tree plots are produced by combiTree and graph the tree structure implied by the clusters combining process.
