Attributing the Smoke Dataset

  1. Follow the steps in Lesson 9.

  2. Use the tigris::states and tigris::counties functions to download geometries for the state boundaries and county boundaries for ID, WA, and OR. (see ?tigris::counties and ?tigris::states to see how to do this)

  3. Summarize the points and the other variables at the county and state level (i.e., combine all of the points in a county/state and recalculate the pm2.5 values, run zonal on the counties etc)

  4. Generate a plot for the new scales of aggregtion and compare the point values to those that come from the new aggregation.
