title: Problems with VennDiagram?
body: <p>I have used the recipe given here with a lot of success.  However, for past few days this does not seem to work. My <code>sessionInfo()</code> looks as follows:</p>
  
  <pre><code>R version 2.15.2 (2012-10-26)

  loaded via a namespace (and not attached):

  </code></pre>
  
  <p>I tried the following, and did not produce any result:</p>
  
  <pre><code> require(VennDiagram)
  
   venn.diagram(list(B = 1:1800, A = 1571:2020),fill = c("red", "green"), alpha = c(0.5, 0.5), cex = 2,cat.fontface = 4,lty =2, fontfamily =3, filename = "trial2.emf")
  </code></pre>
  
  <p>But did not produce any result. </p>
  
  <p>Am I doing anything wrong?</p>
