title: How to insert an element in the middle of a list?
body: <p>I have a list with several elements, say 10. </p>
  
  <pre><code>testList &lt;- split(1:10,1:10)
  </code></pre>
  
  <p>How to insert a new element in the middle of the list, say at position 3?</p>
  
  <p>The brute force way of looping through all the elements will work, but just wondering if there is a more elegant way of doing this?</p>
