R/sagang_fillsinksqmofesp.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 Fill sinks (qm of esp) (sagang:fillsinksqmofesp). ---------------- Arguments ----------------  DEM: DEM 	Argument type:	raster 	Acceptable values: 		- Path to a raster layer FILLED: DEM without Sinks 	Argument type:	rasterDestination 	Acceptable values: 		- Path for new raster layer SINKS: Sinks 	Argument type:	rasterDestination 	Acceptable values: 		- Path for new raster layer DZFILL: Fill Increment 	Default value:	0.01 	Argument type:	number 	Acceptable values: 		- A numeric value 		- field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field 		- expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression

##' @title QGIS algorithm - Fill sinks (qm of esp)
##'
##' @param DEM `raster` - DEM. Path to a raster layer.
##' @param FILLED `rasterDestination` - DEM without Sinks. Path for new raster layer.
##' @param SINKS `rasterDestination` - Sinks. Path for new raster layer.
##' @param DZFILL `number` - Fill Increment. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
##' @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`.
