| polygon-class {RGeostats} | R Documentation |
This class contains the description of a polygon, constituted of one or several polysets.
Objects can be created by calls of the form new("polygon", ...).
Contains a polygon
sets:Object of class "list" List with the two vectors containing the 2-D coordinates of the polygon vertices
polygon[i,j] returns the i-th coordinate (1 or 2) of the j-th vertex of the polygon-class
Same but for assignment
polygon$parameter is used to query the value of parameter from polygon:
npol : Number of vertices
sets : List of polysets
surface : Surface of the Polygon
xlim : Extrema of the bounding box around the Polygon along X
ylim : Extrema of the bounding box around the Polygon along Y
limits : Matrix defining the bounding box
center : Vector defining the gravity center
extends : Vector defining the extension of the bounding box
Same but for assignment
Other functions are available, such as:
polygon.create Create a new polygon-class
polygon.digit Digitize a polygon-class from a graphic
polygon.inside Check if a set of 2-D points belong to a polygon-class or not.
polygon.read Read a Polygon from an ASCII file
polygon.write Write a Polygon in an ASCII file
