This function calculates geodesic distance using the cosine method.
Usage
calcCos(latLongs, r = 6378137)
Arguments
- latLongs
Two column matrix of latitudes/longitudes
- r
Earth radius. Default is WGS-84 radius
Examples
# two-column matrix with latitude/longitude, in degrees
latLong = cbind(runif(n = 5, min = 0, max = 90),
runif(n = 5, min = 0, max = 180))
# cosine distance formula
distMat = calcCos(latLongs = latLong)
