Plot function for cda-class

Description

Plot the learning set (and test set) on the canonical axes obtained by Canonical Discriminant Analysis (function CDA).

Usage

## S3 method for class 'cda'
plot(x, newdata = NULL, axes = 1:2, legendpos = "topleft", ...)

Arguments

x	The classification model (object of class cda-class).
newdata	The test set (matrix or data.frame).
axes	The canonical axes to be printed (numeric vector). Ignored when there is only one, which is what two classes give: the axis is then drawn against the observation index, and the class means as horizontal lines.
legendpos	Position of the legend, as in plotdata.
...	Other parameters, passed to the underlying plot.
