body: <p>I know this has to have been addressed before, but I cannot seem to find an answer that works</p>
  
  <p>I have the columns that I want to test the condition against and I want to remove all rows where their value in any of the three columns is above a given value. </p>
  
  <pre><code>x  a  b  c  d  
  1  2  1  3  4  
  2  3  5  2  2  
  3  3  3  3  2  
  4  1  2  3  3  
  </code></pre>

  <pre><code>x  a  b  c  d
  3  3  3  3  2
  4  1  2  3  3
  </code></pre>
