Methods for Function plot in Package ‘flexclust’

Description

Plot the neighbourhood graph of a cluster solution together with projected data points.

Usage

  ## S4 method for signature 'kcca, missing':
  plot(x, y, which=1:2, project=NULL,
         data=NULL, points=!is.null(data),
         hull=!is.null(data), hull.args=NULL, 
         number = TRUE, simlines=TRUE,
         lwd=1, maxlwd=8*lwd, cex=1.5, numcol="black", nodes=16,
         add=FALSE, xlab="", ylab="", xlim = NULL,
         ylim = NULL, pch=NULL, col=NULL, ...)

  flxColors(n=1:8, saturation=c("full","light"))

Arguments

x an object of class "kcca"
y not used
which Index numbers of dimensions of (projected) input space to plot.
project Projection object for which a predict method exists, e.g., the result of prcomp.
data Data to include in plot.
points Logical, shall data points be plotted?
hull If TRUE, then hulls of confidence regions of the data are plotted. If a function, it is used for plotting the hulls.
hull.args A list of arguments for the hull function.
number Logical, plot number labels in nodes of graph?
numcol, cex Color and size of number labels in nodes of graph.
nodes Plotting symbol to use for nodes if no numbers are drawn.
simlines Logical, plot edges of graph?
lwd, maxlwd Numerical, thickness of lines.
add Logical, add to existing plot?
xlab, ylab Axis labels.
xlim, ylim Axis range.
pch, col, ... Plotting symbols and colors for data points.
n, saturation Index numbers and saturation of colors.

Details

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