ArealSampling-class: Class "ArealSampling"

Description Objects from the Class Slots Methods Author(s) References See Also Examples

Description

This virtual class facilitates the definition of subclasses that will encapsulate the basic information required to define individual areal sampling methods used in forestry.

For example, as detailed in “The ArealSampling Class” vignette, we may define subclasses based on whether the sampling methods are for standing trees or downed logs. Other classes, like fixed-area plots, could span these two main subclasses.

Objects from the Class

A virtual Class: No objects may be created from it.

Slots

description:

Object of class "character": Some descriptive text about this class.
