Union one or more polygons

Description

Union one or more polygons

Usage

union_polygon_list(polygon_list, ...)

Arguments

polygon_list	list object that contains one or more polygons.
...	additional arguments are ignored.

Details

This function takes a list of polygons and iteratively calls polyclip::polyclip(A, B, op="union") to produce a union across one or more polygons, which otherwise only works with two polygons.

Value

object list of polygons
