class to hold linear ring topology (without attributes)
Objects can be created by calls to the function SpatialRings
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
Class "Spatial"
, directly.
Methods defined with class "SpatialRings" in the signature:
signature(obj = "SpatialRings")
: select subset of (sets of) rings; NAs are not permitted in the row index
signature(x = "SpatialRings", y = "missing")
: plot rings in SpatialRings object
signature(obj = "SpatialRings")
: retrieves the bbox element
signature(object = "SpatialRings")
: retrieves the coords element from Ring objects in rings slot
signature(object = "SpatialRings")
: retrieves coordinate names
signature(object = "SpatialRings")
: retrieves the ID element from Ring objects in rings slot
signature(obj="SpatialRings", x="character")
: replaces ID element
signature(from = "SpatialRings", to = "SpatialPoints")
: ...
