title: How do I get a list, sorted by frequency, in R
body: <p>I'm trying to get a list, sorted by frequency, from a data frame.</p>
  
  <pre><code>data &lt;- read.csv('ads.csv')
  write.table(summary(data$Publication.Name), quote = FALSE, sep = ",")
  </code></pre>
  
  <p>I'm not sure summary() is really the best way to get frequencies, I'm open to a better way. How can I sort this by most frequent first?</p>
