trainR: An Interface to the National Rail Enquiries Systems
· 7 min read
The goal of trainR is to provide a simple interface to the
National Rail Enquiries (NRE) systems. There are few data feeds
available, the simplest of them is Darwin, which provides real-time
arrival and departure predictions, platform numbers, delay estimates,
schedule changes and cancellations. Other data feeds provide historical
data, Historic Service Performance (HSP), and much more. trainR
simplifies the data retrieval, so that the users can focus on their
analyses. For more details visit
https://www.nationalrail.co.uk/46391.aspx.
Installation
You can install the released version of trainR from CRAN with:
install.packages("trainR")
And the development version from GitHub with:
# install.packages("devtools")
devtools::install_github("villegar/trainR", "dev")
Setup
Before starting to retrieve data from the NRE data feeds, you must obtain an access token. Visit the following website for details: http://realtime.nationalrail.co.uk/OpenLDBWSRegistration/
Once you have received your access token, you have to store it in the .Renviron file; this can be
done by executing the following command:
trainR::set_token()
This will open a text file, .Renviron, add a new line at the end (as follows):
NRE="<token>"
<token> should be replaced by the access token obtained from the NRE. Save the changes and restart
your R session.
You only need to perform this configuration once.
