SimplyStats Thanksgiving Puzzle

I owe a lot to Jeff Leek and Roger Peng for their great Coursera courses, in which I learned to program in R. They (along with Rafa Irizarry) run the Simply Statistics blog, which I highly reccomend.

Suggestions on how I could have done this differently (or automated solutions) most welcome!
