title: R Likert Package: Increase the facet strip label text size
body: <p>I am using the likert package and followed <a href="https://github.com/jbryer/likert/blob/master/demo/likert.R" rel="nofollow noreferrer">this example</a>. I wanted to use the grouping figure like they did. The group figure looks like this:</p>

  <p>I need to increase the font size of the facet strip labels (for example, "I read only if I have to"). How can I do that in R? </p>
  
  <p>Also, how can we change the facet strip orders? For example, I want the orders be like (2,1,5,3,4, ...). </p>
