<h2>Estrada class</h2>

<h3>Description</h3>

<p>Estrada proposes that graphs can be classified into four different classes. We call this the Estrada class.
These are:
I. Expander-like
II. Cluster
III. Core-Periphery
IV.  Mixed.
</p>


<h3>Usage</h3>

<pre>
estrada.class(G, evthresh = 0.001)
</pre>


<h3>Arguments</h3>

<table summary="R argblock">
<tr valign="top"><td><code>G</code></td>
<td>
<p>a <i>p*p</i> adjacency matrix of a Graph</p>
</td></tr>
<tr valign="top"><td><code>evthresh</code></td>
<td>
<p>tolerance for a zero eigenvalue</p>
</td></tr>
</table>


<h3>Value</h3>

<p>Estrada class (<i>1-4</i>)
</p>
