retrieves spatial bounding box from spatial data

Keywords
methods, spatial
Usage
bbox(obj)
Arguments
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

Value

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

Methods

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"
