dplyr chain filter based on frequency : <pre><code>table(mtcars$cyl)

 4  6  8 
11  7 14 
</code></pre>

<p>Suppose I wanted to filter low frequency terms, in this case less than 10. Is there an elegant dplyr esque way to do this?</p>

<pre><code>mtcars %&gt;% group_by(cyl) %&gt;% filter([???])
</code></pre>

<p>The result would be a data frame with 4 and 8 cyl only, since they both occur 10 or more times.</p>
