bubbleRadviz: A Plotting Function for the Radviz Object

In Radviz: Project Multidimensional Data in 2D Space

A Plotting Function for the Radviz Object

Description

Plots the Dimensional Anchors and projected data points in a 2D space.

Usage

bubbleRadviz(
  x,
  main = NULL,
  group = NULL,
  color = NULL,
  size = c(3, 16),
  label.color = NULL,
  label.size = NULL,
  bubble.color,
  bubble.fg,
  bubble.size,
  scale,
  decreasing,
  add
)

Arguments

x	a radviz object as produced by do.radviz
main	[Optional] a title to the graph, displayed on top
group	the name of the grouping variable used to aggregate the data
color	[Optional] the name of the variable used to color the points
size	the size range for the plot
label.color	the color of springs for visualization
label.size	the size of the anchors (see customizing ggplot2 for details on default value)
bubble.color	deprecated, use geom_point instead
bubble.fg	deprecated, use geom_point instead
bubble.size	deprecated, use geom_point instead
scale	deprecated, use geom_point instead
decreasing	deprecated, use geom_point instead
add	deprecated, use geom_point instead

Details

This function allows for the projection of clusters in Radviz (for example results of the SPADE algorithm), where the cluster size is derived from the number of events that fall into a specific cluster. If color is not specified the grouping variable is used.

Value

the internal ggplot2 object plus added layers, allowing for extra geoms to be added

Examples

data(iris)
das <- c('Sepal.Length','Sepal.Width','Petal.Length','Petal.Width')
S <- make.S(das)
rv <- do.radviz(iris,S)
bubbleRadviz(rv, group='Species')
