  <p>I want a new variable that multiplies the labels with the frequency, so for example the first row would be 1<em>70,105=70,105, and 2 would be 2</em>36,377=72754 and so on. I want my new variable to look like this:</p>
  <p><a href="https://i.stack.imgur.com/BSzNu.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/BSzNu.jpg" alt="enter image description here" /></a></p>
