In Zongzheng/forestSAS: Forest spatial structure analysis systems
nnangle R Documentation
Identify the angle among nearest neighbours
Description
Describes the degree of regularity in the spatial distribution of n trees that are nearest to a reference tree. Moving clockwise around reference tree,the angle was obtained between two adjacent neighbours.
Usage
nnangle(nndist, nnx, nny)
Arguments
nndist
Distance of nearest neighbour
nnx
x coordinate of nearest neighbour
nny
y coordinate of nearest neighbour
Value
The angles obtained between two adjacent neighbours.
