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:
# install.packages("devtools")
devtools::install_github("gavinrozzi/njgeo")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:

this package. All objects are returned as an {sf} object
and a coordinate reference system can be specified via arguments to
repoject the shape into a different CRS.
