title: Replace multiple letters with accents with gsub
body: <p>of course I could replace specific arguments like this:</p>
  
  <pre><code>    mydata=c("á","é","ó")
      mydata=gsub("á","a",mydata)
      mydata=gsub("é","e",mydata)
      mydata=gsub("ó","o",mydata)
      mydata
  </code></pre>
  
  <p>but surely there is a easier way to do this all in onle line, right?
  I dont find the gsub help to be very comprehensive on this. </p>
