Convert DGGRID indices to sf object

This function converts DGGRID indices to an sf object. It requires the dggridR package to be installed.

Usage

par_make_dggrid(x, res = 8L, topology = "HEXAGON")

Arguments

x

sf object.

res

integer(1). DGGRID resolution. Default is 8L.

topology

character(1). Topology type, either "HEXAGON" or "SQUARE". Default is "HEXAGON".

Value

An sf object with polygons representing the DGGRID indices.

Details

dggridR::dgconstruct is used to create a DGGRID object with the specified resolution. All arguments in this function are used as default values other than res and topology.
