title: how to create md5 hash of a column in R?
body: <p>I have a data frame </p>
  
  <pre><code>ID, VID
   1 , xyz-0001
  </code></pre>
  
  <p>I would like to replace <code>VID</code> with md5 hash of <code>VID</code> column value.</p>
  
  <p>How would i do that in R? I looked at <code>digest</code> package but can not figure out how to put that in R Code</p>
  
  <p>Thanks </p>
