Another function to create a gridified shapefile and extract a raster if specified

Description

This function takes in only a shapefile and creates a square or hexagon polygon grid based on a specified grid size

Usage

gengrid2(
  shp_dt = NULL,
  shp_dsn,
  shp_layer,
  grid_size,
  sqr = TRUE,
  pop_raster,
  raster_path = NULL,
  extract_name,
  raster_function = "sum"
)

Arguments

shp_dt	an object of class 'sf' or 'sfc'
shp_dsn	character; the local directory folder in which the shapefile is location. Must be specified when shp_dt is not specified.
shp_layer	character; the layer name for the shapefile. Must be specified with shp_dsn when shp_dt is not specified
grid_size	numeric of length 1; representing the desired size of the grid in meters
sqr	logical; if TRUE, a square grid is created. If FALSE, a hexagonal polygon grid is created
pop_raster	raster; an object of class 'raster'
raster_path	character; if pop_raster is not specified but raster is to read in from file. raster_path is the full name of the raster (including filepath)
extract_name	character of length 1; the name of the indicator to be extracted from the raster
raster_function	function to be applied in extracting raster into created grids
