smoothRadviz: A smoothScatter function for Radviz objects

In Radviz: Project Multidimensional Data in 2D Space

A smoothScatter function for Radviz objects

Description

Plots the Dimensional Anchors and a smoothed color density representation of projected data points in a 2D space.

Usage

smoothRadviz(
  x,
  main = NULL,
  color = "dodgerblue4",
  nbin = 200,
  label.color = NULL,
  label.size = NULL,
  smooth.color,
  max.dens,
  transformation,
  nrpoints,
  ncols,
  bandwidth
)

Arguments

x	a radviz object as produced by do.radviz
main	[Optional] a title to the graph, displayed on top
color	the gradient will be generated from white to color
nbin	the number of equally spaced grid points for the density estimation (see geom_density_2d for details)
label.color	the color of springs for visualization
label.size	the size of the anchors (see customizing ggplot2 for details on default value)
smooth.color	deprecated, see stat_density2d instead
max.dens	deprecated, see stat_density2d instead
transformation	deprecated, see stat_density2d instead
nrpoints	deprecated, see stat_density2d instead
ncols	deprecated, see stat_density2d instead
bandwidth	deprecated, see stat_density2d instead

Value

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