Distance matrix
Distance matrix of a set of points, or between two sets of points
distm(x, y, fun=distGeo)
x |
longitude/latitude of point(s). Can be a vector of two numbers, a matrix of 2 columns (first one is longitude, second is latitude) or a SpatialPoints* object |
y |
Same as |
fun |
A function to compute distances (e.g., distCosine or distGeo) |
Matrix of distances

xy <- rbind(c(0,0),c(90,90),c(10,10),c(-120,-45)) distm(xy) xy2 <- rbind(c(0,0),c(10,-10)) distm(xy, xy2)
