setup_space: Setup spatial bounds of simulation

In mrajeev08/simrabid: Individual-based model of canine rabies

Description

setup_space creates the spatial grid of the simulation from a user defined shapefile and resolution. If vaccination data are aggregated at a larger scale, pass the id column (i.e. numeric id of the administrative unit) to assign each grid cell to. Alternatively if vaccination data are aggregated at the grid cell level or vaccination is absent, then pass NULL to id_col.

Usage

setup_space(shapefile, resolution = 1000, id_col, use_fasterize = FALSE)

Arguments

shapefile	a shapefile (either an sf or sp object) of the area being simulated should be projected in UTM coordinates
resolution	numeric, the resolution in meters
id_col	character, the name of the attribute/column to rasterize the data by, largely for allocating vaccinations
use_fasterize	boolean, if TRUE and class of shapefile is sf will use the fasterize package (if installed)

Details

To do:

• Add examples with sf and sp & different id_col

• Tests: resolution too large? if no fasterize, if no id col

Value

raster of simulation bounds rasterized by the id column specify (i.e. each grid cell allocated to a location)
