Make better maps in R with vector tiles

Vector tiles? When MapQuest and later Google Maps came on the scene we were blown away by the detail, speed, and convenience of “slippy maps” that you could scroll, pan, and drag across. The concept underpinning those maps was the use of tiles: pre-rendered map cells for every specified zoom level that would be loaded by your browser as you scrolled through a map.

After seeing the excellent electoral results maps from the Berliner Morgenpost, I wanted to experiment with a similar approach for an alternative take on my maps of linguistic diversity in Canadian cities.

In a country like Canada with two official languages, a rich history of diverse Aboriginal languages, and a long history of immigration from a wide range of countries and ethno-linguistic cultures, we would expect to see a relatively high score for linguistic diversity.
