title: How to identify the rows with different values compare to other rows?
body: <p>I have the following dataframe in R</p>
  
  <pre><code>ID b  c  d  
  1  33 33 35  
  2  33 33 35  
  3  32 34 36  
  4  33 33 35  
  5  32 33 35  
  6  33 33 35  
  </code></pre>
  
  <p>My desire is to find out the rows with different values compare to other rows. In this case, the rows with different values will be ID3 and ID5.</p>
  
  <p>Can anyone help me on this? </p>
  
  <p>Thanks</p>
