# plot.lda

##### Plot Method for Class 'lda'

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

- Keywords
- multivariate, hplot

##### Usage

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

##### Arguments

- 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

##### Details

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"`

.
