I am trying to use the distHavrsine function in R, inside a loop to calculate the distance between some latitude and longitude coordinates for a several hundred rows. In my loop I have this code:
if ((distHaversine(c(file[i,"long"], file[i,"lat"]),
c(file[j,"long"], file[j,"lat"]))) < 50 )
after which if the distance is less than 50 meters i want it to record those rows, and where the latitude and longitude coordinates it is referencing look like:
0.492399367 30.42530045
and
0.496899361 30.42497045
but i get this error
Error in .pointsToMatrix(p1) : latitude > 90
