title: Notation for fractions (divides by or over) in R and ggplot2
body: <p>I am trying to place one word over another for a title. I mean literally over, not just a 'divides by' sign one value over another (or word) to save space. It is supposed to mean divides by and there needs to be a line.</p>
  
  <p>I cannot find how to do this, can you help?</p>
  
  <p>Thanks,</p>
  
  <p>Chris</p>
