<h2>Plot Method for Class 'lda'</h2>
<h3>Description</h3>
<p>
Plots a set of data on one, two or more linear discriminants.
</p>
<h3>Usage</h3>
<pre>
## S3 method for class 'lda':
plot(x, panel = panel.lda, ..., cex = 0.7, dimen,
abbrev = FALSE, xlab = "LD1", ylab = "LD2")
</pre>
<h3>Arguments</h3>
<table summary="R argblock">
<tr valign="top"><td><code>x</code></td>
<td>
An object of class <code>"lda"</code>.
</td></tr>
<tr valign="top"><td><code>panel</code></td>
<td>
the panel function used to plot the data.
</td></tr>
<tr valign="top"><td><code>...</code></td>
<td>
additional arguments to <code>pairs</code>, <code>ldahist</code> or <code>eqscplot</code>.
</td></tr>
<tr valign="top"><td><code>cex</code></td>
<td>
graphics parameter <code>cex</code> for labels on plots.
</td></tr>
<tr valign="top"><td><code>dimen</code></td>
<td>
The number of linear discriminants to be used for the plot; if this
exceeds the number determined by <code>x</code> the smaller value is used.
</td></tr>
<tr valign="top"><td><code>abbrev</code></td>
<td>
whether the group labels are abbreviated on the plots. If <code>abbrev > 0</code>
this gives <code>minlength</code> in the call to <code>abbreviate</code>.
</td></tr>
<tr valign="top"><td><code>xlab</code></td>
<td>
label for the x axis
</td></tr>
<tr valign="top"><td><code>ylab</code></td>
<td>
label for the y axis
</td></tr>

<h3>Details</h3>
<p>
This function is a method for the generic function
<code>plot()</code> for class <code>"lda"</code>.
It can be invoked by calling <code>plot(x)</code> for an
object <code>x</code> of the appropriate class, or directly by
calling <code>plot.lda(x)</code> regardless of the
class of the object.
</p>
<p>
The behaviour is determined by the value of <code>dimen</code>. For
<code>dimen > 2</code>, a <code>pairs</code> plot is used. For <code>dimen = 2</code>, an
equiscaled scatter plot is drawn. For <code>dimen = 1</code>, a set of
histograms or density plots are drawn. Use argument <code>type</code> to
match <code>"histogram"</code> or <code>"density"</code> or <code>"both"</code>.
