title: How do I include a superscript to texts on a plot on R?
body: <p>I need it to look like this:</p>
  
  <p>R^2 = some values  </p>
  
  <p>And I've tried the code below but it wouldn't work, it came out as "R (expression (^2)) = some values" instead:</p>
  
  <pre><code>text (25, 200, paste ("R (expression (^2)) =", round (rsquarelm2, 2)))
  </code></pre>
