PDF generating has font/library issues

[h2rashee]

Looks like there is some R package bootstrapping issues that the script doesn't auto-handle in the pre-amble.

$ Rscript fisher_crawford.r 
Warning messages:

It looks like you don't have cairo installed on your system, which I believe is required but cannot be installed through R. At the bottom of this page it basically says you may have to install cairo yourself on Mac: https://stat.ethz.ch/R-manual/R-devel/library/grDevices/html/cairo.html

Heh. I did see that page but couldn't find the installation instructions. I had tried installing XQuartz but no dice.

Excuse me for being a noob at R.

Hehe no problem. Unfortunately I don't have a lot of time to help debug this kind of thing at the moment... as I said this isn't particularly related to my code or to R as far as I can tell but to some dependency of a dependency.
