title: Sweave in Rstudio -- no plots showing in pdf
body: <p>Sweave/Latex newbie here. I have no problems generating regular functions outputs, but the plots don't show up. Here's a basic example:</p>
  
  <pre><code>\documentclass{article}
  \begin{document}
  \SweaveOpts{concordance=TRUE}
  
  &lt;&lt;chunk1&gt;&gt;=
  print("Hello World")
  boxplot(rnorm(100))
  @
  
  \end{document}
  </code></pre>
  
  <p>And the corresponding .tex output:</p>
  
  <pre><code>\documentclass{article}
  \usepackage{Sweave}
  \begin{document}
  \input{test2-concordance}
  
  \begin{Schunk}
  \begin{Sinput}
  &gt; print("Hello World")
  \end{Sinput}
  \begin{Soutput}
  [1] "Hello World"
  \end{Soutput}
  \begin{Sinput}
  &gt; boxplot(rnorm(100))
  \end{Sinput}
  \end{Schunk}
  
  \end{document}
  </code></pre>
  
  <p>I am running Rstudio version 0.98.501. I use Texlive, and tried on both Windows and Linux with the same results. What am I missing?</p>
