title: How to get a non-square plot in R?
body: <p>How do I get a rectangular space for a plot (so the x axis is e.g. twice as long as the y axis)??</p>
  
  <p>Right now I am doing </p>
  
  <pre><code>plot(xValues, yValues, type="l" , cex=dotsize ,
       xlim=c(0,max_x), ylim=c(1, max_y) ,
       bty="n" )
  </code></pre>
  
  <p>I tried using pty="m" but that didn't change anything (I guess I do not really understand what it is supposed to do...).
  I do not want the scales to alter, so asp is not what I mean (at least, from what I have tried so far).</p>
  
  <p>So, what I have right now (though it actually a line) is:</p>
  
  <pre><code>|     .
  |   .
  | .
  ________
    1 2 3 
  </code></pre>
  
  <p>and what I want would be somthing like:</p>
  
  <pre><code>|               .
  |         .
  |   .
