This workshop will demonstrate the use of the ggplot2 and ggmaps packages for working with and visualizing geospatial data. Participants will learn how to plot points, line and polygon features on a map, customize symbology, and add reference data like Google Maps and OpenStreetMaps. Geocoding place names and addresses with ggmaps will also be introduced.
Prerequisites: This workshop builds on the methods and tools introduced in the D-Lab workshop Geospatial Data & Maps in R, part 1: the basics. Students should also have basic R experience equivalent to that provided by the D-Lab’s R FUN!damentals workshop series.
Technology requirements: Students should bring a laptop to the workshop with R installed. RStudio is also highly recommended. To follow along with the tutorial please have the following R packages installed: sp, rgdal, RColorBrewer, ggplot2, ggmaps, maps, maptools, dplyr, tidyr, scales, and classInt.
