<h2>
Synthetic Classification Problem
</h2>

<h3>Description</h3>

<p>The <code>synth.tr</code> data frame has 250 rows and 3 columns.
The <code>synth.te</code> data frame has 100 rows and 3 columns.
It is intended that <code>synth.tr</code> be used from training and
<code>synth.te</code> for testing.
</p>


<h3>Usage</h3>

<pre>
synth.tr
synth.te
</pre>


<h3>Format</h3>

<p>These data frames contains the following columns:
</p>

<dl>
<dt><code>xs</code></dt><dd>
<p>x-coordinate
</p>
</dd>
<dt><code>ys</code></dt><dd>
<p>y-coordinate
</p>
</dd>
<dt><code>yc</code></dt><dd>
<p>class, coded as 0 or 1.
