An introduction to leaflet maps in R

Presented September 19, 2017. 

The main goal of this talk is to demonstrate map making in R using leaflet. We will cover trivial and non-trivial examples. I use the data.table package as my default data container and for all data manipulation. 



Sub topics: 

· Examples of various map types: points, choropleths, and heat maps 

· Creating sharable maps in html using knitr 

· Basic minimal project organization for the development of a reproducible map 

· Data acquisition from tigris, the ACS, and the Chicago data portal 

· KDE heat map calculations 



The project and code is available online at https://github.com/geneorama/wnv_map_demo/.
