title: PCA FactoMineR plot data
body: <p>I'm running an R script generating plots of the PCA analysis using <a href="http://factominer.free.fr/" rel="nofollow"><code>FactorMineR</code></a>.</p>
  
  <p>I'd like to output the coordinates for the generated PCA plots but I'm having trouble finding the right coordinates. I found <code>results1$ind$coord</code> and <code>results1$var$coord</code> but neither look like the default plot.</p>
  
  <p>I found 
  <a href="http://www.statistik.tuwien.ac.at/public/filz/students/seminar/ws1011/hoffmann_ausarbeitung.pdf" rel="nofollow">http://www.statistik.tuwien.ac.at/public/filz/students/seminar/ws1011/hoffmann_ausarbeitung.pdf</a>
  and
  <a href="http://factominer.free.fr/classical-methods/principal-components-analysis.html" rel="nofollow">http://factominer.free.fr/classical-methods/principal-components-analysis.html</a>
  but neither describe the contents of the variable created by the PCA</p>
  
  <pre><code>library(FactoMineR)
  data1 &lt;- read.table(file=args[1], sep='\t', header=T, row.names=1)
  result1 &lt;- PCA(data1,ncp = 4, graph=TRUE) # graphs generated automatically
  plot(result1)
  </code></pre>
