The [dplyr two-table verbs vignette](https://dplyr.tidyverse.org/articles/two-table.html) and Jenny Bryan’s [Cheatsheet for dplyr join functions](http://stat545.com/bit001_dplyr-cheatsheet.html) are also great resources. ### gganimate The animations were made possible by the newly re-written [gganimate](https://github.com/thomasp85/gganimate#README) package by [Thomas Lin Pedersen](https://github.com/thomasp85) (original by [Dave Robinson](https://github.com/dgrtwo)). The [package readme](https://github.com/thomasp85/gganimate#README) provides an excellent (and quick) introduction to gganimte.
