Hi Edzer, Roger and list,
is it intended that subset.SpatialPointsDataFrame() returns two additional columns with the
coordinates in the data-slot of it's return value?
data(meuse.grid)
names(meuse.grid)
coordinates(meuse.grid) <- ~x+y
names(meuse.grid)
meuse.grid <- subset(meuse.grid, meuse.grid$dist > 0.01)
names(meuse.grid)
Regards,
Tom
