class-SpatialRingsDataFrame: Class "SpatialRingsDataFrame"

Description Objects from the Class Slots Extends Methods Author(s) See Also Examples

Description

class to hold linear ring topology (without attributes)

Objects from the Class

Objects can be created by calls to the function SpatialRingsDataFrame

Slots

data:

Object of class "data.frame"; attribute table

rings:

Object of class "list"; list elements are all of class Ring-class

bbox:

Object of class "matrix"; see Spatial-class

proj4string:

Object of class "CRS"; see CRS-class

Extends

Class "SpatialRings", directly. Class "Spatial", by class "SpatialRings".

Methods
