Polygons-class: Class "Polygons"
Description
Collection of objects of class "Polygon"
Objects from the Class
Objects can be created by calls to the function Polygons
Slots
Polygons
:- Object of class
"list"
; list with objects
of class Polygon-class plotOrder
:- Object of class
"integer"
; order in which
the Polygon objects should be plotted, currently by order of decreasing size labpt
:- Object of class
"numeric"
; pair of x, y coordinates giving a label point, the label point of the largest polygon component ID
:- Object of class
"character"
; unique identifier string area
:- Object of class
"numeric"
; the gross total planar area of the Polygon list but not double-counting holes (changed from 0.9-58 - islands are summed, holes are ignored rather than subtracted); these values are used to make sure that polygons of a smaller area are plotted after polygons of a larger area, does not respect projection as objects of this class have no projection defined
