plot.cec {CEC}  R Documentation 
Plot CEC Objects
Description
plot.cec
presents the results from the cec
function in the form of a plot. The colors of the data points represent the
cluster they belong to. Ellipses are drawn to represent the covariance
(of either the model or the sample) of each cluster.
Usage
## S3 method for class 'cec'
plot(
x,
col,
cex = 0.5,
pch = 19,
cex.centers = 1,
pch.centers = 8,
ellipses = TRUE,
ellipses.lwd = 4,
ellipses.lty = 2,
model = TRUE,
xlab,
ylab,
...
)
Arguments
x 

col 
A specification for the default plotting color of the points in
the clusters. See 
cex 
A numerical value giving the amount by which plotting text and
symbols should be magnified relative to the default. See 
pch 
Either an integer specifying a symbol or a single character to be
used as the default in plotting points. See 
cex.centers 
The same as 
pch.centers 
The same as 
ellipses 
If this parameter is TRUE, covariance ellipses will be drawn. 
ellipses.lwd 
The line width of the covariance ellipses. See 
ellipses.lty 
The line type of the covariance ellipses. See 
model 
If this parameter is TRUE, the model (expected) covariance will be used for each cluster instead of the sample covariance (MLE) of the points in the cluster, when drawing the covariance ellipses. 
xlab 
A label for the x axis. See plot for more details. 
ylab 
A label for the y axis. See plot for more details.
