title: Changing the legend labels in a windrose from R openair
body: <p>I made a graph using <code>windRose</code> from the <code>openair</code> package. Here is a reproducible example.</p>
  
  <pre><code>library(openair)
  windRose(mydata, ws="ws", wd="wd", breaks=c(0,1.5,3.3,5.4,7.9,10.7), 
               auto.text= FALSE, paddle = FALSE, annotate = FALSE)
  </code></pre>
  
  <p>I found that I can change the legend title, footer and position by <code>key.header</code>, <code>key.footer</code> and <code>key.position</code>. But I would like to change the legend labels, so the "1.5 to 3.3", to be used in another language than English ("1.5 zu 3.3") or for example to "2 Beaufort". Is there an easy way?</p>
