flexclust (version 1.3-3)

image-methods: Methods for Function image in Package `flexclust'

Description

Image plot of cluster segments overlaid by neighbourhood graph.

Usage

## S3 method for class 'kcca':
image(x, which = 1:2, npoints = 100,
         xlab = "", ylab = "", fastcol = TRUE, col=NULL,
         clwd=0, graph=TRUE, ...)

Arguments

x

An object of class "kcca".

which

Index number of dimensions of input space to plot.

npoints

Number of grid points for image.

fastcol

If TRUE, a greedy algorithm is used for the background colors of the segments, which may result in neighbouring segments having the same color. If FALSE, neighbouring segments always have different colors at a speed p

col

Vector of background colors for the segments.

clwd

Line width of contour lines at cluster boundaries, use larger values for npoints than the default to get smooth lines. (Warning: We really need a smarter way to draw cluster boundaries!)

graph

Logical, add a neighborhood graph to the plot?

xlab, ylab, ...

Graphical parameters.

Details

This works only for "kcca" objects, no method is available for "kccasimple" objects.
