ptvapi

This package provides a friendly interface to the Public Transport Victoria (PTV) Timetable API. Results are returned as data frames --- using real-time data where available --- and authentication is handled under the hood.

This package is an unofficial wrapper of the Public Transport Victoria timetable API. The authors of this package are not associated with Public Transport Victoria.

Installing

CRAN version

install.packages("ptvapi")

Development version

remotes::install_github("mdneuzerling/ptvapi")

Authentication

Using the API requires a user ID (also called a devid) and an API key from Public Transport Victoria. These can be requested in an email. Refer to the PTV website for instructions.

The user ID and API key be provided directly to the functions, for example:

routes(
  user_id = 1234567,
  api_key = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
)

Alternatively, this information can be set as environment variables. These can be configured directly within R:

Sys.setenv("PTV_USER_ID" = 1234567)
Sys.setenv("PTV_API_KEY" = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx")

If a user_id or api_key value is not provided to the functions within this package, then they will be retrieved from the "PTV_USER_ID" and "PTV_API_KEY" environment variables, if possible.

Example usage

The code examples below assume that you've set environment variables for authentication.

# tibble of all routes

A note about route types

The API recognises five route types: "Train", "Tram", "Bus", "Vline", and "Night Bus". Many functions have arguments such as route_type and route_types that expect a non-negative integer code representing these route types. To simplify calling the API, these functions will also accept a character description like those above. Under the hood, the functions will translate these descriptions to the non-negative integer codes that the API expects. For example, routes(route_type = "Train") is automatically translated to routes(route_type = 0).

Available functions

All API calls have been implemented. Some API calls have been combined into a single function with arguments, and some have been split into multiple functions. The following functions are available through this package:

• departures
• directions
• directions_on_route
• disruption_information
• disruption_modes
• disruptions
• disruptions_at_stop
• disruptions_on_route
• fare_estimate
• outlets
• outlets_nearby
• patterns
• route_information
• route_types
• routes
• run_information
• runs_on_route
• search_outlets
• search_routes
• search_stops
• stop_information
• stops_nearby
• stops_on_route
