[Tikzdevice-bugs] Error: "TeX capacity exceeded, sorry"

[Cameron Bracken]

That code produces a text file that is 14 MB!! I have noticed that ggplot2
is not the most efficient in the way it does some of its plotting. But
anyway, we have run into this problem with complex graphics before. You need
to increase your tex capacity. See how to do that here:

http://www.latex-community.org/forum/viewtopic.php?f=45&p=19031

I was able to compile your example by setting

main_memory = 100000000

It takes a really long time though and the resulting pdf is still about 4
MB. Hope this helps.
