createSilhouetteProfile: Create cluster silhouette profile plot.

Description

Create cluster silhouette profile plot.

Usage

createSilhouetteProfile(km, baseSize = 12, baseFamily = "serif", title = "Cluster Silhouette Profile (Histogram)", xlab = "Silhouette Value", ylab = "Count", coordFlip = 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.

coordFlip

logical flipped cartesian coordinates so that horizontal becomes vertical, and vertical horizontal (see coord_flip).

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.

Value

ggplot object
