flexclust (version 0.7-0)

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

Description

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

Usage

## S3 method for class 'kcca,missing':
plot(x, y, which=1:2, project=NULL,
         data=NULL, points=!is.null(data), hull=!is.null(data),
         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, ...)

Arguments

x

an object of class "kcca"

y

not used

which

Index number 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.

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.
