Installation

You should first install the development version of the httr package.

devtools::install_github("hadley/httr")

Then go ahead and install the ubeR package.

devtools::install_github("DataWookie/ubeR")

Uber Endpoints

Details of the various endpoints offered by the Uber API can be found here.

These endpoints have already been implemented:

GET /v1/products
GET /v1/products/{product_id}
GET /v1/estimates/price
GET /v1/estimates/time
GET /v1.2/history
GET /v1.1/history
POST /v1/requests
GET /v1/requests/current
DELETE /v1/requests/current
GET /v1/payment-methods
GET /v1/places/{place_id}
PUT /v1/places/{place_id}

The following endpoints still need to be managed:

PATCH /v1/requests/current
GET /v1/requests/{request_id}
PATCH /v1/requests/{request_id}
DELETE /v1/requests/{request_id}
GET /v1/requests/{request_id}/map
GET /v1/requests/{request_id}/receipt
POST /v1/reminders
GET /v1/reminders/{reminder_id}
PATCH /v1/reminders/{reminder_id}
DELETE /v1/reminders/{reminder_id

Usage

Here's an example of taking the ubeR package through its paces. First load the package.

library(ubeR)

Next get the ID and secret used for authenticating with Uber. Below these are retrieved from the environment.

UBER_CLIENTID = Sys.getenv("UBER_CLIENTID")
UBER_CLIENTSECRET = Sys.getenv("UBER_CLIENTSECRET")

Authenticate.

uber_oauth(UBER_CLIENTID, UBER_CLIENTSECRET, FALSE)

Retrieve information on the user and his methods of payment.

uber_me()
uber_payment_methods()

Retrieve the predefined locations for the authenticated account.

uber_places_get()
uber_places_get("home")
uber_places_get("work")

Retrieve history of recent rides as a data.frame.

uber_history()

Find the cars in the vicinity of a specific location or focus on a particular car.

uber_products(latitude = -33.925278, longitude = 18.423889)
uber_products(product_id = "91901472-f30d-4614-8ba7-9fcc937cebf5")

General estimate for a trip between two locations.

uber_requests_estimate(start_latitude = -33.899656, start_longitude = 18.407663,
                       end_latitude = -33.927443, end_longitude = 18.457557)

Price estimate for a trip specified by either latitude and longitude or address.

uber_estimate_price(start_latitude = -33.899656, start_longitude = 18.407663,
                    end_latitude = -33.927443, end_longitude = 18.457557)
uber_estimate_price(start_address = "37 Beach Road, Mouille Point, Cape Town",
                    end_address = "100 St Georges Mall, Cape Town City Centre, Cape Town, 8001")

Time estimate for a trip specified by either latitude and longitude or address.

uber_estimate_time(start_latitude = -33.899656, start_longitude = 18.407663)
uber_estimate_time(start_address = "37 Beach Road, Mouille Point, Cape Town")

Request a ride. The package is currently wired to the sandbox server, so this will not result in a real ride. We'll shortly point the code at the real server.

uber_requests(start_address = "37 Beach Road, Mouille Point, Cape Town",
              end_address = "100 St Georges Mall, Cape Town City Centre, Cape Town, 8001")

Get information on current request and delete it.

uber_requests_current()
uber_requests_current_delete()
