smoothRadviz {Radviz}

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)
