sp_contig: Assign the locations of a regular grid to folds in contiguous...

In mrfoliveira/Evaluation-procedures-for-forecasting-with-spatio-temporal-data: Evaluation procedures for forecasting with spatio-temporal data

Description

Assigns the locations of a data frame into contiguous blocks folds for cross-validation. Assumes the sites are sorted (e.g., left to right, bottom to top). WARNING: Works well for perfect squares that can be divided into nfolds perfect squares ONLY.

Usage

sp_contig(nfolds, nsites, grid.h = sqrt(nsites), grid.w = sqrt(nsites))

Arguments

nfolds	number of folds to divide the space into
nsites	number of locations in the regular grid
grid.h	height of the grid (in number of sites). Default is sqrt(nfolds)
grid.w	width of the grid (in number of sites). Default is sqrt(nfolds)

Value

a vector with the fold assignment of each location
