hereR

R interface to the HERE REST APIs:

(1) geocode and autocomplete addresses or reverse geocode POIs using the Geocoder API;

(2) routing directions, travel distance or time matrices and isolines using the Routing API;

(3) real-time traffic flow and incident information from the Traffic API;

(4) weather forecasts, reports on current weather conditions and astronomical information at a specific location from the Destination Weather API.

Locations, routes and isolines are returned as sf objects and tables as data.table objects.

Installation

You can install the released version of hereR from CRAN with:

install.packages("hereR")

… or install the development version from GitHub with:

devtools::install_github("munterfinger/hereR")

Application credentials

In order to use the functionality of the hereR package, application credentials (APP ID and APP CODE) for a HERE project of type REST & XYZ HUB API/CLI have to be provided. These credentials will be set for the current R session and will be used to authenticate in the reqeusts to the HERE REST APIs. To set the credentials, please use:

Examples

• Geocode addresses:
  locs <- geocode(addresses = c("Schweighofstrasse 190, Zürich, Schweiz", "Hardstrasse 48, Zürich, Schweiz"))
  
  
• Autocomplete addresses:
  suggestions <- autocomplete(addresses = c("Schweighofstrasse", "Hardstrasse"))
  
  
• Reverse geocode POIs:
  addresses <- reverse_geocode(poi = locs)
  
  
• Construct a route between points:
  routes <- route(start = locs_start, destination = locs_dest, mode = "car")
  
  
• Create a route matrix between points:
  route_matrix <- route_matrix(start = locs, mode = "car")
  
  
• Request weather observations at specific locations:
  observations <- weather(poi = locs, product = "observation")
  
  
• Request weather forecast at specific locations:
  forecast <- weather(poi = locs, product = "forecast_hourly")
  
  
• Request astronomical information at specific locations:
  astronomy <- weather(poi = locs, product = "forecast_astronomy")
  
  
• Request weather alerts at specific locations:
  alerts <- weather(poi = locs, product = "alerts")
  
  
• Get real-time traffic flow in a specific area:
  flow <- traffic(aoi = area, product = "flow")
  
  
• Get traffic incidents in a specific area:
  incidents <- traffic(aoi = area, product = "incidents")
