title: ggplot multiple grouping bar
body: <p>I would like to know how to get 9 grouping bar plot (3x3) togheter. </p>
  
  <p>My CSV : <code>data &lt;- read.csv("http://pastebin.com/raw.php?i=6pArn8GL", sep = ";")</code></p>
  
  <p>The 9 plots should be groupes according "Type" A to I.</p>
  
  <p>Then each grouped bar plot should have the frequency on the y axis, the x axis is grouped by 1 pce to 6 pce and subdiveded by year.</p>
  
  <p>I have the following example on Excel (cf. image) and would like to create the same result on r with ggplot. Is it possible?</p>
  
  <p>Thanks</p>
