title: ggplot2 pdf import in Adobe Illustrator missing font AdobePiStd
body: <p>I created several simple ggplot2 plots and saved them to PDF files using the following commands:</p>
  
  <pre><code>p &lt;- ggplot(plotobject, aes(x=Pos, y=Pval),res=300)
  ggsave(plot=p,height=6,width=6,dpi=200, filename="~/example.pdf")
  </code></pre>
  
  <p>If I now open this example.pdf in Adobe Illustrator I get the following error:</p>
  
  <blockquote>
    <p>The font AdobePiStd is missing.  Affected text will be displayed using
    a substitute font.</p>
  </blockquote>
  
  <p>Is there a way in ggplot2 to specify a font (I presume this is for the dots/points) that Adobe will understand or otherwise is there a way to get this font working in Adobe? </p>
  
  <p>/edit just to clarify, the text/labels/titles are all just fine its the dots that are missing for the font 
  /edit2 I got a working solution by just using the EPS output in ggsave, but still would love to find out a way to also be able to just open/import ggplot2 plots in PDF format directly in AI</p>
