Examples
#Create a new raster and set all its values to unity.
r <- raster(nrows=18, ncols=36)
r <- setValues(r,rep(1,ncell(raster)))
#Create a Transition object from the raster
tr <- transition(r,mean,4)
#Create two sets of coordinates
sP1 <- SpatialPoints(cbind(c(65,5,-65),c(55,35,-35)))
sP2 <- SpatialPoints(cbind(c(50,15,-40),c(80,20,-5)))
#Calculate the RSP distance between the points
rSPDistance(tr, sP1, sP2, 1)
