Description

Spatial k-folds.

Usage

spat.folds(coords, nfolds = 10, size = 1000)

Value

A list with nfolds elements. Each elements contains a list with two elements, the first is the indices of the training set and the second contains the indices of the test set.

Arguments

coords

A matrix with the coordinates of the locations. The first column is the latitude and the second is the longitude.

nfolds

The number of spatial folds to create.

size

A numeric value of the specified range by which blocks are created and training/testing data are separated. This distance should be in metres. If you have big regions you should consider increasing this number. For more information see the package blockCV.
