Dummy data

Load dummy data that help understand the methods of geoimp.

Usage

dummy_data(res = 1, n_poly = 2)

Arguments

res

Resolution of the local population raster. Defaults to 1x1 cells.

n_poly

Number of areal polygons. Can either be one or two polygons.

Value

A list with three datasets:

• survey: A fake survey dataset of class sf containing point data and two attribute columns on place types and income.

• areas: One or two (depending on n_poly) polygons of class sfc that symbolize administrative areas.

• pop: A fake population raster of class SpatRaster.

• income: A fake income raster of class SpatRaster.

All datasets have a local CRS with coordinates ranging from 0 to 4.
