forestSAS (version 1.0.1)

ideal: A forest spatial structure index characterizing distribution of ideal state for tree attributies.

Description

Analyze the distribution of ideal state for tree attributies in a neighborhood unit according to the characteristics of the tree attributies,such as tree health,climax species distribution,etc.in spatial micro-environment.which clearly define the ideal degree of tree attributies for a reference tree and its four nearest neighbors.

Usage

ideal(x, para)

Arguments

x

A vector composed by 5 tree attributies.

para

Ideal state of tree attributies.

Value

Result will retrun five values,0,0.25,0.5,0.75,1,which means none,one, two, three or four ideal tree attributies of nearest neighbors for reference tree,respectively.
