| SpatialPolygons-class {sp} | R Documentation |
class to hold polygon topology (without attributes)
Objects can be created by calls to the function SpatialPolygons
polygons:"list"; list elements are
all of class Polygons-classplotOrder:"integer"; integer array
giving the order in which objects should be plotted bbox:"matrix"; see Spatial-class proj4string:"CRS"; see CRS-class
Class "Spatial", directly.
Methods defined with class "SpatialPolygons" in the signature:
signature(obj = "SpatialPolygons"): select subset of (sets of) polygons; NAs are not permitted in the row index\signature(x = "SpatialPolygons", y = "missing"):
plot polygons in SpatialPolygons object\signature(object = "SpatialPolygons"): summarize objectRoger Bivand
