[mark88232]

I executed following R codes.

library(osrm)

data("com")

iso <- osrmIsochrone(loc = src[6,], breaks = seq(from = 0,to = 30, by = 5))

but I got a following error when using osrmIsoChrone function

osrmTable function returns an error: 
Error: Something went wrong. It could be that the URL sent to the OSRM public API is too long. 
         Try to enter less sources or destinations.

Error in (function (classes, fdef, mtable)  : 
  unable to find an inherited method for function ‘coordinates’ for signature ‘"NULL"’

Hello,
This is probably linked to a problem on the demo server. See issue #4101 (Project-OSRM/osrm-backend#4101)

As they say :

Keep in mind the demo server has basically no uptime guarantees. We try to keep it stable and working but it's running the latest commits and osm planet - so there will be hiccups every now and then.

Here's how to run a routing engine locally on a small extract if that's good enough for you:
