The Cost of True Love (a.k.a. The Tidy — and expensive! — Twelve Days of Christmas)

December 5, 2017

I’m in the market for Christmas presents for my true love, @mrshrbrmstr, and thought I’d look to an age-old shopping list for inspiration. Just what would it set me back if I decided to mimic the 12 Days of Christmas in this modern day and age?

Let’s try to do the whole thing in R (of course!).

We’ll need to:

  • Grab the lyrics
  • Parse the lyrics
  • Get pricing data
  • Compute some statistics
  • Make some (hopefully) pretty charts

This one was complex enough formatting-wise that I needed to iframe it below. Feel free to bust out of the iframe at any time.

Some good follow-ups to this (if you’re so inclined) would be to predict prices next year and/or clean up the charts a bit.

Grab the code up on GitHub.
