Section 12 Mapping

In this section, we continue with the goal of discovery, this time using maps to visualize data.

• Describe and measure
  • Has the U.S. population increased?
• Explain, evaluate, and recommend (study of causation)
  • Does expanding Medicaid improve health outcomes?
• Predict
  • Who will win the next election?
• Discover
  • How do policies diffuse across states?

Our goals

• Visually communicate social science information using maps
• Learn how to use the library(maps) package with library(ggplot) (QSS 5.3.2)
  • Our code also builds on Kieran Healy’s book and the tidyverse version of QSS from Jeffrey Arnold here
• Discover patterns in our spatial world!!

Along the way, we will learn to merge data and use the %in% function.
