title: Plot over multiple pages
body: <p>I have the <code>facet_wrap</code> function to make multiple graphs (n=~51) but they all appear on one page. Now after searching, I found out that <em>ggplot2</em> can't place graphs on multiple pages. </p>
  
  <p>Is there a way to do this? I looked at this question (<a href="https://stackoverflow.com/questions/19059826/multiple-graphs-over-multiple-pages-using-ggplot">Multiple graphs over multiple pages using ggplot</a>) and tried out the code, with little success. </p>
  
  <p>Here is my code for my graphs, it produces ~51 graphs on one page, making them very small and hard to see, if I could print this to 1 graph per page in a pdf, that would be great:</p>
  
  <pre><code>ggplot(indbill, aes(x = prey, y = weight), tab) +
  geom_polygon(aes(group = load, color = capture), fill = NA, size = 0.75) +
  facet_wrap(~ individual) +
  theme(axis.ticks.x = element_blank(),
      axis.text.x = element_text(size=rel(0.5)),
      axis.ticks.y = element_blank(),
      axis.text.y = element_blank()) +
  xlab("") + ylab("") +
  guides(color = guide_legend(ncol=2)) +
  coord_radar()
  </code></pre>
  
  <p>If someone could write up a little code and explain it to me, that would be great.</p>
