ideal {forestSAS} | R Documentation |
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.
