Maps with ggplot2

• What we'll do
Amy Szczepanski will teach us about making maps with ggplot2!

We can take advantage of ggplot2's ability to plot points, lines, and polygons to draw maps without relying on specialized GIS tools. We will combine data from several sources to make a map showing major geographical features in San Diego, median property values per census tract, and the flight paths of planes departing San Diego International airport. The presentation will start by plotting points in the (x, y) plane with ggplot2 and will review the key features of this package. Next, we will use ggmap to easily put those points in context on a map. Finally, we will use shapefiles to color in regions in our maps.
