Tools for geocoding addresses using the State of New Jersey’s official geocoding service & accessing spatial data.
You can install the development version of njgeo from GitHub with:
This package supports freely geocoding addresses in New Jersey. No API keys are required and this does not depend on any commercial services.

The batch_geocode_addresses() and batch_geocode_sl() functions can batch geocode up to 1000 addresses at a time. The first function expects multiple columns of data to geocode the address, while the sl version requires an address in single column format.
Provide a point to get matching addresses:
