library(osrm)
iso <- osrmIsochrone(loc = c(1.300658, 103.839696), breaks = seq(from = 0,to = 30, by = 5))
Gives me the following error:
Error in spTransform(xSP, CRSobj, ...) :
error in pj_transform: latitude or longitude exceeded limits
Can someone please tell me what I am doing wrong, and how to fix this error? Many thanks
