R/sagang_removeboundarypolygons.R

In JanCaha/r_package_qgis: An extension of package "qgisprocess" providing direct R functions for QGIS functions

##' QGIS Algorithm provided by SAGA Next Gen Remove boundary polygons (sagang:removeboundarypolygons). ---------------- Arguments ----------------  POLYGONS: Polygons 	Argument type:	source 	Acceptable values: 		- Path to a vector layer RESULT: Result 	Argument type:	vectorDestination 	Acceptable values: 		- Path for new vector layer METHOD: Method 	Default value:	0 	Argument type:	enum 	Available values: 		- 0: (0) Extent 		- 1: (1) Polygon Boundary 	Acceptable values: 		- Number of selected option, e.g. '1' 		- Comma separated list of options, e.g. '1,3'

##' @title QGIS algorithm - Remove boundary polygons
##'
##' @param POLYGONS `source` - Polygons. Path to a vector layer.
##' @param RESULT `vectorDestination` - Result. Path for new vector layer.
##' @param METHOD `enum`  of `("(0) Extent", "(1) Polygon Boundary")` - Method. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param ... further parameters passed to `qgisprocess::qgis_run_algorithm()`
##' @param .complete_output logical specifying if complete out of `qgisprocess::qgis_run_algorithm()` should be used (`TRUE`) or first output (most likely the main) should read (`FALSE`). Default value is `TRUE`.
##' @param .quiet logical specifying if parameter `.quiet` for `qgisprocess::qgis_run_algorithm()` Default value is `TRUE`.
##' @param .messages logical specifying if messages from `qgisprocess::qgis_run_algorithm()` should be printed (`TRUE`) or not (`FALSE`). Default value is `FALSE`.
