## retrieves spatial coordinates

### Description

retrieves spatial coordinates from spatial data

### Methods

obj = "list"
  list with (at least) two numeric components of equal length
obj = "data.frame"
  data.frame with at least two numeric components
obj = "matrix"
  numeric matrix with at least two columns
obj = "SpatialPoints"
  object of, or deriving from, SpatialPoints
obj = "SpatialPointsDataFrame"
  object of, or deriving from, SpatialPointsDataFrame
obj = "Line"
  object of class Line; returned value is matrix
obj = "Lines"
  object of class Lines; returned value is list of matrices
obj = "SpatialLines"
  object of, or deriving from, SpatialLines; returned value is list of lists of matrices
obj = "GridTopology"
  object of, or deriving from, GridTopology
obj = "GridTopology"
  object of, or deriving from, GridTopology
obj = "SpatialPixels"
  object of, or deriving from, SpatialPixels
obj = "SpatialPixelsDataFrame"
  object of, or deriving from, SpatialPixelsDataFrame
obj = "SpatialGrid"
  object of, or deriving from, SpatialGrid
obj = "SpatialGridDataFrame"
  object of, or deriving from, SpatialGridDataFrame

### Methods for "coordinates<-"

object = "data.frame", value="ANY"
  promote data.frame to object of class SpatialPointsDataFrame-class, by specifying coordinates; see coordinates
