Function to calculate geospatial distance between two points (lat,long) using R [duplicate]
Loading the geosphere package you can use a number of different functions
library(geosphere)distm(c(lon1, lat1), c(lon2, lat2), fun = distHaversine)Also:
distHaversine()distMeeus()distRhumb()distVincentyEllipsoid()distVincentySphere()...
Agree with @PereG on answer above, but think that the order of latitude and longitude is the other way around: lon, lat. This will affect your results for distance matrix. So correct is:
library(geosphere)distm (c(lon1, lat1), c(lon2, lat2), fun = distHaversine)Source: ftp://cran.r-project.org/pub/R/web/packages/geosphere/geosphere.pdf
