title: How to delete rows from a data.frame, based on an external list, using R?
body: <p>This might be an easy question but i still need some help for using R.</p>
  
  <p>I have a data.frame (main_data), lets say..</p>
  
  <pre><code>NAMES   AGE     LOC
  Jyo     23      Hyd
  Abid    27      Kar
  Ras     24      Pun
  Poo     25      Goa
  Sus     28      Kar
  </code></pre>
  
  <p>I wish to remove a few rows based on a list of names. So lets say I have another list of table as follows:</p>
  
  <pre><code>NAMES_list
  Jyo
  Ras
  Poo
  </code></pre>
  
  <p>So based on this list, if any of the names match to my above "main_data" table, then I would like to remove the whole row contianing them, so the result should be as follows</p>
  
  <pre><code>NAMES   AGE     LOC
  Abid    27      Kar
  Sus     28      Kar
  </code></pre>
  
  <p>Can anyone help me how to achive this using R? 
  Thanks in advance.. :)</p>
