title: How to avoid showing headers in STOUT of R data.table?
body: <p>I am trying to avoid showing headers in R's STOUT of <code>data.table</code> output. Akrun says in the related thread the the null route may be possible with <code>print</code>. </p>
  
  <blockquote>
    <p>If you are not okay with the NULL route, then you may have to create a custom function for print by modifying the existing print </p>
