contour.radviz: Plots the Dimensional Anchors and density lines for projected...

In Radviz: Project Multidimensional Data in 2D Space

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

Description

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

Usage

## S3 method for class 'radviz'
contour(
  x,
  ...,
  main = NULL,
  color = NULL,
  size = 0.5,
  label.color = NULL,
  label.size = NULL,
  contour.color,
  contour.size,
  point.color,
  point.shape,
  point.size,
  n,
  drawlabels,
  drawpoints,
  add
)

Arguments

x	a radviz object as produced by do.radviz
...	further arguments to be passed to or from other methods (not implemented)
main	[Optional] a title to the graph, displayed on top
color	the variable in the Radviz projection used to color the contours
size	The thickness of contour lines
label.color	the color of springs for visualization
label.size	the size of the anchors (see customizing ggplot2 for details on default value)
contour.color	deprecated, see geom_density2d instead
contour.size	deprecated, see geom_density2d instead
point.color	deprecated, see geom_density2d instead
point.shape	deprecated, see geom_density2d instead
point.size	deprecated, see geom_density2d instead
n	deprecated, see geom_density2d instead
drawlabels	deprecated, see geom_density2d instead
drawpoints	deprecated, see geom_density2d instead
add	deprecated, see geom_density2d instead

Value

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