Hi Chris, As Nate mentioned, the best thing is to run your local copy of OSRM. I found the easiest way is to run a Docker image, you can find the back-end here:
https://hub.docker.com/r/osrm/osrm-backend/ For R, I find the best package to manage the geometries is sf ( https://r-spatial.github.io/sf/index.html). You will have to work a bit to put together the requests to the OSRM API and send it to the localhost and then you can parse the results with sf::st_read or manually. Once you have your routes as LINESTRING geometries you can save them to shapefile or gpkg with sf::st_write.
