keepOrigGeom: Keep original geometries of 'sf' objects

In reproducible: Enhance Reproducibility of R Code

Keep original geometries of sf objects

Description

When intersections occur, what was originally 2 polygons features can become LINESTRING and/or POINT and any COLLECTIONS or ⁠MULTI-⁠ versions of these. This function evaluates what the original geometry was and drops any newly created different geometries. For example, if a POLYGON becomes a COLLECTION of MULTIPOLYGON, POLYGON and POINT geometries, the POINT geometries will be dropped. This function is used internally in postProcessTo().

Usage

keepOrigGeom(newObj, origObj)

Arguments

newObj	The new, derived sf object
origObj	The previous, object whose geometries should be used.

Value

The original newObj, but with only the type of geometry that entered into the function.
