IFNknn: k-nearest neighbours for IFN plots

In miquelcaceres/IFNdyn: IFN forest dynamics and scenario analysis

Description

Builds a weighted neighbouring object containing the k-nearest neighbours as well as the distances to them, from a matrix of longitude/latitude coordinates.

Usage

IFNknn(coords, k = 57, verbose = TRUE)

Arguments

coords	Matrix of plot coordinates in longitude and latitude, with plot IDs as row names.
k	Number of neighbours to determine.
verbose	Boolean flag to turn on console output informing of the calculation process.

Value

An object of class list with elements 'neighbours' and 'distances'. Plot IDs are stored in attribute 'IDs'

Examples

# Load example plot coordinates
data(examplePlotCoords)
examplePlotCoords

# Build neighbour object (only one neighbour)
nb = IFNknn(examplePlotCoords, k = 1)
nb
