title: Display Correlation Tables as Descending List
body: <p>When running cor() on a times series with a lot of variables, I get a table back that has a row and column for each variable, showing the correlation between them.</p>
  
  <p>How can I view this table as a list from most correlated to least correlated (eliminating all NA results and results that map back to themselves (i.e. the correlation of A to A)). I would also like to count inverse (negative) results as absolute values, but still show them as negative.</p>
  
  <p>So the desired output would be something like:</p>
  
  <pre><code>A,B,0.98
  A,C,0.9
  C,R,-0.8
  T,Z,0.5
  </code></pre>
