<h2>Combining Objects</h2>


<h3>Description</h3>

<p>
Provides the S4 methods to combine several objects based on
<code><a href="itemMatrix-class.html">itemMatrix</a></code> into a single object.
</p>
<p>
Note, use <code><a href="sets.html">union</a></code> rather than <code>c</code> to combine several mined
<code><a href="itemsets-class.html">itemsets</a></code> (or <code><a href="rules-class.html">rules</a></code>) into a single
set.
</p>


<h3>Usage</h3>

<pre>
## S4 method for signature 'itemMatrix':
c(x, ..., recursive = FALSE)

## S4 method for signature 'transactions':
c(x, ..., recursive = FALSE)

## S4 method for signature 'rules':
c(x, ..., recursive = FALSE)

## S4 method for signature 'itemsets':
c(x, ..., recursive = FALSE)
</pre>


<h3>Arguments</h3>

<table summary="R argblock">
<tr valign="top"><td><code>x</code></td>
<td>
first object.</td></tr>
<tr valign="top"><td><code>...</code></td>
<td>
further objects of the same class as <code>x</code> to be combined.</td></tr>
<tr valign="top"><td><code>recursive</code></td>
<td>
a logical. If <code>recursive=TRUE</code>, 
the function recursively
descends through lists combining all their elements into a
vector.</td></tr>
</table>

<h3>Value</h3>

<p>
An object of the same class as <code>x</code>.</p>

<h3>Examples</h3>

<pre>
data("Adult")

## combine transactions
a1 &lt;- Adult[1:10]
a2 &lt;- Adult[101:110]

aComb &lt;- c(a1, a2)
summary(aComb)

## combine rules
r1 &lt;- apriori(Adult[1:1000])
r2 &lt;- apriori(Adult[1001:2000])
rComb &lt;- unique(c(r1, r2)) 
rComb
