Geocode addresses and institutions with Google's API

I'm using Google's API even though it's not free because it works better than OpenStreetMap when it comes to addresses and institution names.

geocode_address(df, address_col)

Arguments

df

A data frame that has a column for addresses.

address_col

Column for addresses. Tidyeval is used here so it doesn't need to be quoted.

Value

A data frame with all columns of df, but with city, state, and country added. Only rows with valid geocoding results are returned.
