predictor.nn.indices: Calculate spatial index position of nearest neighbors

In SantanderMetGroup/downscaleR: A climate4R package for statistical downscaling <http://meteo.unican.es/climate4r>

Calculate spatial index position of nearest neighbors

Description

Calculate spatial index position of nearest neighbors

Usage

predictor.nn.indices(vars = NULL, n = NULL, x, y)

Arguments

vars	Character vector of the names of the variable(s) to be used as local predictors
n	Integer vector. Number of nearest neighbours to be considered for each variables in vars. Its length must be either 1 –in case there is one single local predictor variable or the same number of neighbours is desired for every local predictor variable– or equal the length of vars, to consider a varying number of neighbours for each local predictor variable.
x.grid	The (multi)grid containing the predictors
y.grid	The grid containing the predictand

Value

A list of matrices (rows = local neighbors, cols = predictand points). The list is of the same length as the number of local predictor variables chosen
