Description

This function generates a spatial rectangular grid from the slot boundary of an object of class prevR; function used in particular by the methods kde(), krige() and idw().

Usage

make.grid.prevR(object, nb.cells = 100, cell.size = NULL)

Arguments

object	object of class prevR.
nb.cells	number of cells on the longest side of the studied area (unused if cell.size is defined).
cell.size	size of each cell (in the unit of the projection).

Details

This function generates a spatial rectangular grid, each cell corresponding to the center of a square of side cell.size. If cell.size is not defined, side of cells will be calculated as the longest side of the slot boundary of object divided by nb.cells.

Value

Object of class sf::sfc (simple feature geometry list column).
