title: ggplot2 embed all used fonts in pdf, R
body: <p>I am plotting some figures using <code>qplot</code> and <code>ggplot</code>. Prior to the plot I call <code>pdf()</code> and save the plot with <code>dev.off()</code>. I would have to embed all the fonts in the pdf. How can I do this? Either at the time of the plot or post-process the pdf's to embed the fonts?</p>
