Erase one geometry from another using Saga GIS

Description

This function erase one geometry from another. The projection must be identical.

Usage

rsaga_erase(x, y, method = "1", split = "0", attributes = "1",
  env.rsaga = RSAGA::rsaga.env(), check.geom = TRUE, quiet = TRUE)

Arguments

x	object of class sf. First element: Should be either line or polygon
y	object of class sf. Second element: Always polygon.
method	method of erase. Either "1": , or "2": Line-Polygon Intersection. Default: "1"
split	Set to "1", if multi-part polygons should be splitted to single-part polygons. Default: "0"
attributes	attributes inherited to intersection result. [0] polygon, [1] line, [2] line and polygon. Default: "1"
env.rsaga	SAGA GIS environemnt. Default: RSAGA::rsaga.env()
check.geom	If set to TRUE then geometry is checked with sf::st_is_valid(). If there are invalid geometries, geometries are repaired using lwgeom::st_make_valid(). Default: TRUE

Value

Geometry of class sfc
