## 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.
