One thing I have noticed when reading other peoples’ R code is that their functions are often a lot longer than mine.

Le Monde puzzle [#814]

The #814 Le Monde math puzzle was to find 100 digits (between 1 and 10) such that their sum is equal to their product.

This Gist shows how to scrape “stats” and .PNG images from, erm, Bulbapedia, run a simple dimensionality reduction on those “stats,” and plot all 151 original Pokemon. I don’t know much about Pokemon, so I can’t vouch for...
