Class "SpatialRingsDataFrame"

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".
