Produce Pairwise Scatterplots from an 'lda' Fit

Pairwise scatterplot of the data on the linear discriminants.

# S3 method for lda
pairs(x, labels = colnames(x), panel = panel.lda,
     dimen, abbrev = FALSE, ..., cex=0.7, type = c("std", "trellis"))

Arguments

x	Object of class "lda".
labels	vector of character strings for labelling the variables.
panel	panel function to plot the data in each panel.
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.
...	additional arguments for pairs.default.
cex	graphics parameter cex for labels on plots.
type	type of plot. The default is in the style of pairs.default; the style "trellis" uses the Trellis function splom.

Details

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