Joining Spatial Data

We can join data onto the data frame stored in the data slot of our SpatialPolygonsDataFrame. In this chapter, we are interested in the mean income at the zip code level as reported by the IRS. Once we have the income data joined onto the information in the data slot of shp we can map the mean income of zip codes on our leaflet map.

A data frame called nc_income has been loaded for you. Let's get started by taking a look at the nc_income data. Then we'll join it onto the information in the data slot of shp and see if there are any zip codes in our data that are missing income information.
