od2line() throws an error if only one origin-destination relation is selected about stplanr

Awesome, glad it worked. Do close this issue if fixed for you and wish me luck updating od2line() to build on the 'engine' of {od} as a backend!

In fact may be useful to keep open to track updating od2line().

Hey @yannikbuhl thanks for the message and detailed example.

Quickfire follow-up question: have you tried od::od_to_sf() from the {od} package?

At some point I'd like to replace the current od2line() with a small wrapper to the more efficent implementation in the newer package: https://github.com/itsleeds/od

Hi Robin, thanks for the quick response. I have not tried od::od_to_sf() yet but I definitely will, thanks for the suggestion. And I'll let you know if that solves the problem :)

A quick test with the minimal reproducible example tells me that replacing od2line with od_to_sf does indeed work and return a LINESTRING geometry. I will test this when back at work with the data I'm working with but I'd be optimistic. Thanks so much for your suggestion!

desire_lines_london2 <- od::od_to_sf(od_london[1,], centroids_london)
