title: Insert List as Column into Dataframe R
body: <p>I am trying to append a column to the end of my dataframe. The column is supposed to be filled with list <code>id</code>. However, when I write <code>w &lt;-cbind(w, id)</code>, it instead prints the entirety of <code>id</code> into each cell of the data frame.</p>
  
  <p>Current output:</p>
  
  <pre><code>    optOne%    optTwo%    Neither%    TotalCount    id
