haversine R Documentation
Great-circle (Haversine) distance
Description
Vectorized great-circle distance between longitude/latitude points. Arguments are
recycled to a common length, so any may be length 1.
Usage
haversine(lon1, lat1, lon2, lat2, radius = 6371.0088)
Arguments
lon1, lat1, lon2, lat2
Numeric vectors of coordinates in decimal degrees.
radius
Sphere radius in the desired output units. Defaults to the mean Earth
radius, 6371.0088 km, so distances are returned in kilometres.
Value
A numeric vector of distances. NA in any coordinate gives NA.
Examples
haversine(0, 0, 0, 1) # ~111 km per degree of latitude
haversine(7.4, 9.1, 8.5, 12.0) # Abuja-ish to Kano-ish
