title: What does |> (pipe greater than) mean in R?
body: <p>I have recently come across the code <code>|&gt;</code> in R. It is a vertical line character (pipe) followed by a greater than symbol.</p>
  <p>Here is an example:</p>
  <pre><code>mtcars |&gt; head()
  </code></pre>
  <p>What is the <code>|&gt;</code> code doing?</p>
