createClusterPlot: Create clusters' properties plot.

In toaster: Big Data in-Database Analytics that Scales with Teradata Aster Distributed Platform

Description

Create clusters' properties plot.

Usage

createClusterPlot(km, baseSize = 12, baseFamily = "serif",
  title = paste("Cluster Properties Plot"), xlab = "cluster",
  ylab = "value", border = TRUE, colorByCluster = TRUE, ticks = FALSE,
  defaultTheme = theme_tufte(base_size = baseSize, base_family = baseFamily,
  ticks = ticks), themeExtra = NULL)

Arguments

km	an object of class "toakmeans" returned by computeKmeans.
baseSize	theme base font size.
baseFamily	theme base font family.
title	plot title.
xlab	a label for the x axis, defaults to a description of x.
ylab	a label for the y axis, defaults to a description of y.
border	boolean indicates to use border around plotting area. In case of facets border is around each facet.
colorByCluster	logical: color corresponds to clusters or properties.
ticks	logical Show axis ticks using default theme settings (see defaultTheme)?
defaultTheme	plot theme settings with default value theme_tufte. More themes are available here: ggtheme (by ggplot2) and ggthemes.
themeExtra	any additional theme settings that override default theme.
