gama (version 1.0.3)

gama.plot.partitions: Plots results of a Gama clustering.

Description

This function takes a gama object and plots the partitions found by the algorithm. The partitions will be coloured accordingly the distribution of the clusters.

Usage

gama.plot.partitions(gama.obj = NULL, view = "pca", …)

Arguments

gama.obj

an object of type 'gama' generated by an appropriate gama call to gama clustering.

view

the representation used to plot the partitions. If 'pca' is used, the function will perform a Principal Component Analysis over the dataset and plot the two main components. If 'total.sum' is used, the function will sum all dimensions for each observation and plot this sum, highlighting its partitions. If omitted, the default value 'pca' will be used.

…

other arguments that user may pass to the function.
