Plots a set of data on one, two or more linear discriminants.

```
# S3 method for lda
plot(x, panel = panel.lda, …, cex = 0.7, dimen,
abbrev = FALSE, xlab = "LD1", ylab = "LD2")
```

x

An object of class `"lda"`

.

panel

the panel function used to plot the data.

…

additional arguments to `pairs`

, `ldahist`

or `eqscplot`

.

cex

graphics parameter `cex`

for labels on plots.

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`

.

xlab

label for the x axis

ylab

label for the y axis

This function is a method for the generic function
`plot()`

for class `"lda"`

.
It can be invoked by calling `plot(x)`

for an
object `x`

of the appropriate class, or directly by
calling `plot.lda(x)`

regardless of the
class of the object.

The behaviour is determined by the value of `dimen`

. For
`dimen > 2`

, a `pairs`

plot is used. For `dimen = 2`

, an
equiscaled scatter plot is drawn. For `dimen = 1`

, a set of
histograms or density plots are drawn. Use argument `type`

to
match `"histogram"`

or `"density"`

or `"both"`

.
