title: How to use plot.window? (in R)
body: <p>When I run the following code:</p>
  
  <pre><code>xlim &lt;- c(-30,30)
  ylim &lt;- c(-5,5)
  plot.window(xlim , ylim )
  plot.new()
  points(1,1)
  points(0,0)
  </code></pre>
  
  <p>For some reason, all I'm getting is a graphic window where it seems that the <code>xlim/ylim</code> are <code>c(0,1)</code>.</p>
  
  <p>Did I miss something about how to use the <code>plot.window</code> ?</p>
  
  <p>Thanks.</p>
