inset	Inset configuration; see configure_inset().

Value

A copy of x with the geometry replaced by the transformed version.

Examples

library(sf)

nc <- sf::st_read(system.file("shape/nc.shp", package = "sf"), quiet = TRUE)
cfg <- configure_inset(
  centre = st_sfc(st_point(c(-82, 35)), crs = 4326),
  scale = 2,
  translation = c(10, -60),
  radius = 50,
  units = "mi")
