R/sagang_invertdatanodata.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 Invert data/no-data (sagang:invertdatanodata). ---------------- Arguments ----------------  INPUT: Grid 	Argument type:	raster 	Acceptable values: 		- Path to a raster layer OUTPUT: Result 	Argument type:	rasterDestination 	Acceptable values: 		- Path for new raster layer VALUE: Data Value 	Default value:	1 	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 - Invert data/no-data
##'
##' @param INPUT `raster` - Grid. Path to a raster layer.
##' @param OUTPUT `rasterDestination` - Result. Path for new raster layer.
##' @param VALUE `number` - Data Value. 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`.
