Arguments

ELEVATION

raster - Elevation. Path to a raster layer.

WEIGHTS

raster - Weights. Path to a raster layer.

DISTANCE

rasterDestination - Flow Path Length. Path for new raster layer.

DIRECTION

enum of ("(0) downstream", "(1) upstream") - Direction of Measurement. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.

further parameters passed to qgisprocess::qgis_run_algorithm()

.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.

.quiet

logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.

.messages

logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
