R/sagang_geographiccoordinategrids.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 Geographic coordinate grids (sagang:geographiccoordinategrids). ---------------- Arguments ----------------  GRID: Grid 	Argument type:	raster 	Acceptable values: 		- Path to a raster layer LON: Longitude 	Argument type:	rasterDestination 	Acceptable values: 		- Path for new raster layer LAT: Latitude 	Argument type:	rasterDestination 	Acceptable values: 		- Path for new raster layer

##' @title QGIS algorithm - Geographic coordinate grids

##' @param GRID `raster` - Grid. Path to a raster layer.
##' @param LON `rasterDestination` - Longitude. Path for new raster layer.
##' @param LAT `rasterDestination` - Latitude. 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`.
