<h2>Mining Associations with Eclat</h2>
<h3>Description</h3>
<p>
Mine frequent itemsets with the Eclat algorithm.
This algorithm uses simple intersection operations for equivalence
class clustering along with bottom-up lattice traversal.
</p>
<h3>Usage</h3>
<pre>
eclat(data, parameter = NULL, control = NULL)
</pre>
<h3>Arguments</h3>
<table summary="R argblock">
<tr valign="top"><td><code>data</code></td>
<td>
object of class
<code><a href="transactions-class.html">transactions</a></code> or any data structure
which can be coerced into
<code><a href="transactions-class.html">transactions</a></code> (e.g., binary
<code>matrix</code>, <code>data.frame</code>).</td></tr>
<tr valign="top"><td><code>parameter</code></td>
<td>
object of class
<code><a href="ASparameter-class.html">ECparameter</a></code> or named list (default
values are: support 0.1 and maxlen 5)</td></tr>
<tr valign="top"><td><code>control</code></td>
<td>
object of class
<code><a href="AScontrol-class.html">ECcontrol</a></code> or named list for
algorithmic controls.</td></tr>
</table>
<h3>Details</h3>
<p>
Calls the C implementation of the Eclat algorithm by Christian
Borgelt for mining frequent itemsets.
</p>
<h3>Value</h3>
<p>
Returns an object of class <code><a href="itemsets-class.html">itemsets</a></code>.</p>
