New Orleans and Normalization

28 April 2020 My post about Apple’s mobility data from a few days ago has been doing the rounds. (People have been very kind.)

His discussion of Small Multiples and Normalization is really worth your while.

Apple's COVID Mobility Data

23 April 2020 Update I’ve added a GitHub repository containing the code needed to reproduce the graphs in this post, as what’s shown here isn’t self-contained.

Covdata Package

10 April 2020 The covdata logo Partly because it grew out of a few code-throughs I was doing, but mostly as a classroom exercise, I pulled together a small data package for R called covdata, available at https://kjhealy.github.io/covdata/. It contains COVID-19 data from three sources: National level data from the European Centers for Disease Control. State-level data for the United States from the COVID Tracking Project. State-level and county-level data for the United States from the New York Times.
