Hi,

I found your package and it overlaps with some of my research and two packages I've been working on:

https://github.com/ropensci/opentripplanner

https://github.com/ITSLeeds/UK2GTFS

I was wondering if you are still developing propeR and if there was anything useful we could learn from each other.

To use propeR as part of a pipeline it would be easier if the output could be written to an R object file

Accelerator student would find it useful for the polylines to be outputted from pointToPointLoop()

I am trying to use propeR to find the walking distance between a set of postcodes and a list of bus stops. I have the OTP server installed (using OpenTripPlanner) and it correctly gives walking routes between two points in the browser interface.

However, when I try to use any of the properR functions I get the following:

pointToPointNearest(output.dir = "D:\Data Science Stuff\TRACC replacement with PropeR\GreaterLondonOutput",
otpcon = otpcon,
originPoints = postcodes_2018_London,
destinationPoints = railstops_London,
journeyReturn = F,
modes = 'WALK',
nearestNum = 1,)
Now running the propeR pointToPointNearest tool.
Parameters chosen:
KNN nearest number: 1 (2584 calls)
Return Journey: FALSE
Date and Time: 2020-04-15 14:45:44
Creating 2584 point to point connections, please wait...
Error in parse_url(url) : length(url) == 1 is not TRUE

Unfortunately I can find nothing about this error anywhere, so I turn to you for help!

I am running R version 3.6.3, R Studio version 1.2.5042, and am doing this on a Windows 10 machine with 8GB RAM.

Hi,

Thanks for creating this!

When I run the isochrone tool with the test origin and destinations dataset, I get the following error:
"Error in ogrInfo(dsn = dsn, layer = layer, encoding = encoding, use_iconv = use_iconv, :
Cannot open data source"

Specifically, the command I'm running is:
"isochrone(userdir, otpcon = otpcon, originPoints = originPoints, originPointsRow= 2, destinationPoints = destinationPoints, destinationPointsRow = 2, startDateAndTime = '2019-06-05 17:00:00', modes = 'WALK, TRANSIT', mapOutput = T, isochroneCutOffMax = 90, isochroneCutOffMin = 30, isochroneCutOffStep = 30)"

The graph is working, since I can run the pointToPoint function with the same arguments.

Sorry if I'm missing something obvious.

Also, on a separate topic (but it's so minor that it wasn't worth opening a new issue): in the destination.csv dataset provided, I think the column "Name" should be called "name", otherwise it gives the following error when importing: "Error in order(data_points$name) : argument 1 is not a vector".

Thanks,
Stef
