Quadrat-class: Class "Quadrat"

In pgs: Precision of Geometric Sampling

Description

Extend class "Figure". Representation of planar quadrats (rectangles).

Objects from the Class

Objects can be created by calls of the form new("Quadrat", ...). It is recommended to use the generator Quadrat.

Slots

dimspace:

Object of class "numeric". Dimension of the space where the quadrat lies. Equal to 2.

coord:

Object of class "matrix". A 2x1 matrix containing the Cartesian coordinates of a vertex of the quadrat. The opposite vertex is defined as the origin.

Extends

Class "Figure", directly.

Methods

content

signature(x = "Quadrat"): compute the quadrat area.

covariogram

signature(x = "Quadrat", f = "function"): covariogram for a Quadrat object.

plot

signature(x = "Quadrat", y = "missing"): plot a Quadrat object. The extra argument origin (default: null vector) may be used to plot the quadrat translated by the vector origin. If the extra argument add (default: FALSE) is TRUE, the quadrat is added to the current plot.

print

signature(x = "Quadrat"): print a Quadrat object.
