pointRelascope-class: Class '"pointRelascope"': Point Relascope Sampling

In sampSurf: Sampling Surface Simulation for Areal Sampling Methods

Description

A subclass of "ArealSampling" that can be used to create objects that encapsulate all the parameters necessary for point relascope sampling of down woody debris.

Objects from the Class

Objects can be created by calls of the form new("pointRelascope", ...), and while this is reasonable with this class because there are no graphical slots, it is still not recommended. The preferred method for creating new objects is via the pointRelascope constructor.

Slots

In addition to those slots in class "ArealSampling," the following are defined...

angleDegrees:

Object of class "numeric": The relascope angle in degrees such that 0<ν ≤ 90 degrees.

angleRadians:

Object of class "numeric": The relascope angle in radians.

phi:

Object of class "numeric": The area factor multiplier, φ, for angle ν, as described in the references below.

slFactor:

Object of class "numeric": The squared length factor, L, defining the constant amount of length-square per unit area (acre or hectare) as described in the references below.

rwFactor:

Object of class "numeric": The reach:width ratio or factor that makes it simpler to keep track of some of the more useful relascope angles, especially when constructing a relascope.

Extends

Class "ArealSampling", directly.

Methods
