title: Rename dataset based on external feature dataset
body: <p>I have this sample dataset:</p>
  <pre><code>v1 v2 v3
  2 3 4
  5 6 7
  </code></pre>
  <p>And a feature dataset</p>
  <pre><code>v1 v2
  1 weight
  2 height
  3 age
  </code></pre>
  <p>can you please advise the best way to rename the dataset columns based on the feature dataset?</p>
  <p>thanks!</p>
