x 
see Methods section below. 
y 
currently not used. 
pos 
a desired row number in 
s 
a desired number of clusters to be plotted. The default value is 
what 
a character vector giving the plot types. One of 
nrow 
a desired number of rows in which the empirical and predictive densities are to be plotted. The default value is 
ncol 
a desired number of columns in which the empirical and predictive densities are to be plotted. The default value is 
npts 
a number of points at which the predictive densities are to be plotted. The default value is 
n 
a number of observations to be plotted. The default value is 
cex 
a numerical value giving the amount by which the plotting text and symbols should be magnified
relative to the default, see also 
fg 
a colour used for things like axes and boxes around plots, see also 
lty 
a line type, see also 
lwd 
a line width, see also 
pty 
a character specifying the type of the plot region to be used. One of 
tcl 
a length of tick marks as a fraction of the height of a line of the text, see also 
plot.cex 
a numerical vector giving the amount by which plotting characters and symbols should be
scaled relative to the default. It works as a multiple of 
plot.pch 
a vector of plotting characters or symbols, see also 
contour.drawlabels 
logical. The contours are labelled if 
contour.labcex 

contour.method 
a character specifying where the labels will be located. The possible values
are 
contour.nlevels 
a number of desired contour levels. The default value is 
...
