## Makefiles and RMarkdown

Quite some time ago (October 2013, according to Amazon), I bought a copy of “Reproducible Research with R and RStudio” by Christopher Gandrud. And it was awesome. Since then, I’ve been using knitr and RMarkdown quite a lot. However, until recently, I never bothered with a makefile. At the time, I had assumed that it [...]

## NFL Code on Github

I've made some revisions and simplifications to the code to compile NFL data. It's now all out on Github for anyone to play with in advance of the Superbowl. In the meantime, here's a lovely picture comparing every team's offense- as measured by total offensive yards- against their defenders.

## NFL Prediction – Algorithm 1

So I tidied the code up a bit from last time; no more for loop. Actually, I tidied it up a lot. My goal had been to arrange the data in such a way that I could get a simple moving average of the score difference for each team. That wound up being a semi-lengthy [...]

Because it's for stat nerds and because I was curious, I went looking for some baseball data to analyze. I found loads of it here, but [...]
