title: Hide labels points in a FactoMineR PCA plot
body: <p>I did a PCA with FactoMineR package on data like this :</p>
  
  <pre><code>&gt; data
        1  2  3  4  5
  1000 15  4 14  6 13
  1001 22 11 22 12 24
  1002 15  7 19  9 10
  1003 15  6 20 10 10
  1004 12  3  5  4 11
  1005 22 11 30 12 25
  1006 13 12 24 25 21
  1007 24 12 26  9 14
  1008 21 11 24  7 18
  1009 27  4 28 10 20
  </code></pre>
  
  <p>I then plot results like this :</p>
  
  <pre><code>C = as.factor(c(rep("one", 5), rep("two", 5)))
  res = PCA(data, graph=F)
  plot(res, col.ind=C)
  </code></pre>

  <p>I want to hide points labels and put a legend for each color, but I don't know how to. If someone knows.</p>
