generate_grid: Create a regular grid using spdep package

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

Description

Create a regular grid with a certain number of locations, returning each location's position and neighbour matrices of order 0 and 1.

Usage

generate_grid(Nsites, grid.h = ceiling(sqrt(Nsites)),
  grid.w = ceiling(sqrt(Nsites)))

Arguments

Nsites	Number of locations in the grid
grid.h	Height of the grid (in number of locations). Defaults to sqrt(Nsites)
grid.w	Width of the grid (in number of locations). Defaults to sqrt(Nsites)

Value

A list with slots sites – a data frame with columns id, x and y –, and klist – a list of neighbour matrices of order 0 and 1 where the values are calculated using functions from spdep package.
