Methods for retrieving the geometry from a composite (geometry + attributes) object
geometry retrieves the SpatialXxx object from a SpatialXxxDataFrame object, with Xxx Lines, Points, Polygons, Grid, or Pixels. geometry<- converts a data.frame into a Spatial object.
geometry(obj) geometry(obj) <- value
obj |
in case of assignment, a data.frame, else an object of class Spatial |
value |
object of class Spatial |
