hexplot: A hexplot function for Radviz objects

In yannabraham/Radviz: Project Multidimensional Data in 2D Space

A hexplot function for Radviz objects

Description

Plots the Dimensional Anchors and a hexplot-based density representation of projected data points in a 2D space.

Usage

hexplot(
  x,
  main = NULL,
  nbins = 30,
  color = NULL,
  label.color = NULL,
  label.size = NULL,
  mincnt,
  style
)

Arguments

x	a radviz object as produced by do.radviz
main	[Optional] a title to the graph, displayed on top
nbins	the number of equally spaced bins for the binning computation (see geom_hex for details)
color	if color is not NULL and corresponds to one of the channels in the hexcols slot of the Radviz object, cells will be colored using colors in the hexcols slot
label.color	the color of springs for visualization
label.size	the size of the anchors (see customizing ggplot2 for details on default value)
mincnt	deprecated, see stat_summary_hex instead
style	deprecated, see stat_summary_hex instead

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)
hexplot(rv,color='Sepal.Length')
