title: Excel VBA - If cell is an integer, delete the entire row
body: <p>I have been trying to use some snippets on how to delete entire rows on Excel VBA, but I can't modify them to include the "IsNumber" verification.</p>
  
  <p>I need to be able to choose an active area, like:</p>
  
  <pre><code>Set r = ActiveSheet.Range("A1:C10")
  </code></pre>
  
  <p>And as it goes through row after row (and checking every cell of the area), delete the entire row if a there is a number on a cell.</p>
  
  <p>For example:</p>
  
  <pre><code>NA NA NA 21
  NA 22 NA 44
  00 NA NA NA
  NA NA NA NA
  55 NA NA NA
  </code></pre>
  
  <p>The macro would then delete all the rows, except for the 4th one which is </p>
  
  <pre><code>NA NA NA NA
  </code></pre>
