title: Trouble with findAssocs from package tm
body: <p>I am attempting to find words associated with a particular word in a term document matrix using the tm package.</p>
  
  <p>I am using <code>findAssocs</code> to do this. Arguments for <code>findAssocs</code> are:</p>
  
  <ul>
  <li>x: A term-document matrix.</li>
  <li>term: A character holding a term.</li>
  <li>corlimit: A numeric for the lower correlation bound limit. </li>
  </ul>
  
  <p>I am consistently getting <code>numeric(0)</code> as my result </p>
  
  <p>Example:</p>
  
  <pre><code>findAssocs(test.dtm, "investment", 0.90)
  &gt;numeric(0)
  </code></pre>
  
  <p>Does anyone have familiarity with <code>findAssocs</code> and know what I am doing wrong? Or does anyone know more broadly what the <code>numeric(0)</code> result could mean?</p>
  
  <p>Thank you very much in advance for any help. </p>
