Plot Method for Class 'lda'

Plots a set of data on one, two or more linear discriminants.

Keywords
multivariate, hplot
Usage
## S3 method for class 'lda':
plot(x, panel = panel.lda, \dots, cex = 0.7, dimen,
     abbrev = FALSE, xlab = "LD1", ylab = "LD2")
Arguments
x
An object of class "lda".
panel
the panel function used to plot the data.
...
additional arguments to pairs, ldahist or eqscplot.
cex
graphics parameter cex for labels on plots.
dimen
The number of linear discriminants to be used for the plot; if this exceeds the number determined by x the smaller value is used.
abbrev
whether the group labels are abbreviated on the plots. If abbrev > 0 this gives minlength in the call to abbreviate.
xlab
label for the x axis
ylab
label for the y axis
Details

This function is a method for the generic function plot() for class "lda". It can be invoked by calling plot(x) for an object x of the appropriate class, or directly by calling plot.lda(x) regardless of the class of the object.

The behaviour is determined by the value of dimen. For dimen > 2, a pairs plot is used. For dimen = 2, an equiscaled scatter plot is drawn. For dimen = 1, a set of histograms or density plots are drawn. Use argument type to match "histogram" or "density" or "both".
