I’ve always wanted one of those wall maps that you can push pins into to show where all you’ve been. However, with college and grad school and whatnot, I’ve never really had the energy to put one up, since I know I’ll just have to take it down the next time I move. Then, something occurred to me:
I like maps. I like traveling. I like R. So why not spend a night putting them all together?
Lots of little things happen in grad school that take you by surprise but really shouldn’t. One of those things for me happened after I finished all of my coursework.

You can find the R code I used to generate the images on Github.
I started out by grabbing all the tweets containing the official conference tag (#SPSA2016).
