Generate Random Points with sf

Source: R/engine.R
engine_sf_random.Rd

Uses sf::st_sample() to produce points and spatial joins with input shp. Each engine function takes the same arguments and produces comparable outputs.

Usage

engine_sf_random(shp, col)

Arguments

shp

input shp with sf geometry.

col

character column name to produce points with

Value

tibble with sf geometries

Examples

set.seed(1)
data('suffolk')
engine_sf_random(suffolk[16:20,], 'pop_nhpi')
