Produce Pairwise Scatterplots from an 'lda' Fit

Description

Pairwise scatterplot of the data on the linear discriminants.

Usage

## S3 method for class '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.
