title: How to print a number as exponent in R
body: <p>Figures can be displayed as exponent in unicode, like ¹. How can I use that to convert an arbitrary number to a string with exponent characters, and print that with R? </p>
  
  <p>I can print figures 1 and 2 using <a href="http://en.wikipedia.org/wiki/Unicode_subscripts_and_superscripts" rel="nofollow">http://en.wikipedia.org/wiki/Unicode_subscripts_and_superscripts</a> but the other figures and minus doesn't work.</p>
  
  <p>FWIW, I use Rstudio on Windows.</p>
