Code and data building the graphics and analysis for this post on my personal page. I used data from Kaggle.com representing UFO sightings across the US, and analyzed it on a geographic basis as well as from a more standard regression approach. This was a toy project, but it helped teach me how to use two really awesome packages (tidycensus, and leaflet).
The code on my personal page is written as an RMarkdown report, but I've stripped out the code to present it here. Additionally I demo'd some of the code used to build the choropleth map for the Ann Arbor R User Group-- you can look at the slides here.
