Minkowski distances from a Spatial* or Spatial*DataFrame object
1 | mink.dists(swdf1, swdf2, pwr, scale, weight)
|
swdf1 |
- First Spatial*DataFrame object |
swdf2 |
- Second Spatial*DataFrame object (if omitted, defaults to the same value as |
pwr |
- Minkowski exponent |
scale |
- allows re-scaling eg: value of 1000 means distances in km if coordinates of |
weight |
- weight for each element in swdf1 (the demand locations) |
Distance matrix (if swdf1
or swdf2
not SpatialPoints*,
distances are based on points obtained from coordinates
function)
1 2 3 4 | data(meuse)
coordinates(meuse) <- ~x+y
d1 <- mink.dists(meuse,pwr=1,scale=1000) # Taxicab metric
d2 <- mink.dists(meuse,pwr=Inf,scale=1000) # Works for limiting case
