title: R equivalent of Python 'pass' statement
body: <p>Python has a <a href="http://www.tutorialspoint.com/python/python_pass_statement.htm" rel="noreferrer"><code>pass</code> statement</a>, a null operation, which can be a useful placeholder before code is complete, for example in Python:</p>
  
  <pre><code>def example_function():
      pass
      # stuff to do here
  </code></pre>
  
  <p>Is there an equivalent in R? Thank you.</p>
