title: Adding custom stopwords in R tm
body: <p>I have a Corpus in R using the <code>tm</code> package. I am applying the <code>removeWords</code> function to remove stopwords</p>
  
  <pre><code>tm_map(abs, removeWords, stopwords("english")) 
  </code></pre>
  
  <p>Is there a way to add my own custom stop words to this list?</p>
