title: Generate a QQ Plot for testing a geometrically distributed sample
body: <p>I have a sample of n elements generated in R with</p>
  
  <pre><code>sim.geometric &lt;- function(n)
  {
      u &lt;- runif(n)
      10*u/log(0.5)
  }
  </code></pre>
  
  <p>for which i want to test its distribution, specifically if it indeed follows a geometric distribution. I want to generate a QQ PLot but have no idea how to. Can you help?</p>
  
  <p>Thanks in advance.</p>
