Creating the Intersection of Two Spatial Polygons Data Frames using sf functions

Description

This uses sf::st_intersection to find ONLY the intersecting geometry of two SPDFs and return a single attribute variable from each.

Usage

sf_intersect(
  polygons1,
  polygons2,
  polygons1_attribute,
  polygons2_attribute,
  polygons1_attribute_output = NULL,
  polygons2_attribute_output = NULL,
  projection = NULL
)

Arguments

polygons1	Spatial polygons data frame. One of the two sets of geometry to intersect. polygons1@data must contain a variable with the name given as polygons1_attribute.
polygons2	Spatial polygons data frame. One of the two sets of geometry to intersect. polygons2@data must contain a variable with the name given as polygons2_attribute.
polygons1_attribute	Character string. The name of the variable in polygons1@data for the output to inherit values from.
polygons2_attribute	Character string. The name of the variable in polygons2@data for the output to inherit values from.
polygons1_attribute_output	Optional character string. The name of the variable in the output for the values inherited from polygons1. If NULL then the name from polygons1_attribute will be used. Defaults to NULL
polygons2_attribute_output	Optional character string. The name of the variable in the output for the values inherited from polygons2. If NULL then the name from polygons2_attribute will be used. Defaults to NULL
projection	Optional CRS object. Used as the projection for both polygons1 and polygons2. If NULL then the polygons@proj4string will be used instead. Defaults to NULL.
