R/sagang_gridsfromclassifiedgridandtable.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 Grids from classified grid and table (sagang:gridsfromclassifiedgridandtable). ---------------- Arguments ----------------  TABLE: Table 	Argument type:	source 	Acceptable values: 		- Path to a vector layer ID_FIELD: Attribute 	Argument type:	field 	Acceptable values: 		- The name of an existing field 		- ; delimited list of existing field names CLASSES: Classes 	Argument type:	raster 	Acceptable values: 		- Path to a raster layer GRIDS: Grids 	Argument type:	rasterDestination 	Acceptable values: 		- Path for new raster layer

##' @title QGIS algorithm - Grids from classified grid and table
##'
##' @param TABLE `source` - Table. Path to a vector layer.
##' @param ID_FIELD `field` - Attribute. The name of an existing field. ; delimited list of existing field names.
##' @param CLASSES `raster` - Classes. Path to a raster layer.
##' @param GRIDS `rasterDestination` - Grids. Path for new raster layer.
##' @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`.
