Tools for geocoding addresses using the State of New Jersey’s official geocoding service & accessing spatial data.
Installation
You can install njgeo from CRAN using
install.packages("njgeo")You can install the development version of njgeo from GitHub with:
# install.packages("devtools")
devtools::install_github("gavinrozzi/njgeo")Find all matching address candidates for an address

It is possible to batch geocode up to 1000 addresses at once using the two batch geocoding functions provided by the package.
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.
Reverse Geocoding
Provide a point to get matching addresses:
point <- st_point(c(-74.44513, 40.49297))
reverse_geocode(point)
#> njgeo: downloading data
#> Address Neighborhood City Subregion Region Postal

#> PostalExt CountryCode Match_addr
#> 1 1900 33 Livingston Avenue, New Brunswick, NJ, 08901
#> Loc_name
#> 1 NJ_Geocode_MulShape and boundary files
You can easily obtain spatial boundary data for use in projects via 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.
