title: Rotating axis labels in lattice() package - R
body: <p>I case of built-in R plotting function I can change orientation of axis labels with <code>las</code> parameter, which takes values : <code>{0, 1, 2, 3}</code>. How to achive the same with plotting functions from <code>lattice()</code> ? 
  I don't see any difference between :</p>
  
  <pre><code>set.seed(22342317);levelplot(matrix(runif(100),10,10),las=0)
  set.seed(22342317);levelplot(matrix(runif(100),10,10),las=1)
  set.seed(22342317);levelplot(matrix(runif(100),10,10),las=2)
  set.seed(22342317);levelplot(matrix(runif(100),10,10),las=3)
  </code></pre>
  
  <p>I've tried also with <code>las</code> as parameter of <code>par()</code>, but output is the same.</p>
