`bbox.Rd`

retrieves spatial bounding box from spatial data

`bbox(obj)`

- obj
object deriving from class "Spatial", or one of classes: "Line", "Lines", "Polygon" or "Polygons", or ANY, which requires obj to be an array with at least two columns

- obj = "Spatial"
object deriving from class "Spatial"

- obj = "ANY"
an array with at least two columns

- obj = "Line"
object deriving from class "Line"

- obj = "Lines"
object deriving from class "Lines"

- obj = "Polygon"
object deriving from class "Polygon"

- obj = "Polygons"
object deriving from class "Polygons"

two-column matrix; the first column has the minimum, the second the maximum values; rows represent the spatial dimensions
