title: From one vector delete all elements of another vector in r
body: <p>I have 2 vectors</p>
  
  <pre><code>vec_1
   [1]  2  3  4  5  6  7  8  9 10 11 12 13 14  2  3  4  5  6  7  8  9 10 11 12 13 14  2  3  4  5  6  7  8  9
  [35] 10 11 12 13 14  2  3  4  5  6  7  8  9 10 11 12 13 14
  
  vec_2
   [1] 12  3 13  3 14  4 10  8  9  5  7  5 13 11  6 10  8  8 14 12  6 11  8  5  3  6
  </code></pre>
  
  <p>I want to delete all elements of <code>vec_2</code> from <code>vec_1</code>
  And sure, that function <code>setdiff</code> is not the case,because, for example, in <code>vec_2</code> there are two 10s values. And I want to delete only to 10(not all four values of 10).</p>
  
  <p>EDITED: expected output:</p>
  
  <pre><code>vec_1
  [1] 2 2 2 2 3 4 4 4 5 6 7 7 7 9 9 9 10 10 11 11 12 12 13 13 14 14
  </code></pre>
  
  <p>How can i do this in r?</p>
