`pairs.lda` 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.
