Plot a biplot of a clustering solution on the current graphics device.
1 2 3 4 5 
pc 
The 
clsAsgn 
A vector containing the cluster assignment for each record in the clustering data. 
data.pts 
If 
centroids 
If 
choices 
length 2 vector specifying the components to plot. 
scale 
The variables scaled by 
pc.biplot 
If true, then 
var.axes 
If 
col 
A vector of length 2 giving the colours for the first and
second set of points respectively (and the corresponding axes). If a
single colour is specified it will be used for both sets. If
missing the default colour is looked for in the

cex 
The character expansion factor used for labelling the points. The labels can be of different sizes for the two sets by supplying a vector of length two. 
xlabs 
A vector of character strings to label the first set of
points: the default is to use the row dimname of 
ylabs 
A vector of character strings to label the second set of
points: the default is to use the row dimname of 
expand 
An expansion factor to apply when plotting the second set of points relative to the first. This can be used to tweak the scaling of the two sets to a physically comparable scale. 
arrow.len 
The length of the arrow heads on the axes plotted in

xlim, ylim 
Limits for the x and y axes in the units of the first set of variables. 
main, sub, xlab, ylab, ... 
graphical parameters. 
This function is a reworking of biplot
in order to allow the cluster
centroids of a clustering solution to be displayed as well as the individual
data points. If both data.pts
and centroids
are set to
FALSE
then only the variable directional vectors are displayed.
Graphical parameters can also be given to biplot
.
a plot is produced on the current graphics device.
