)raster - Slope. Path to a raster layer.
raster - Catchment Area. Path to a raster layer.
rasterDestination - LS Factor. Path for new raster layer.
enum of ("(0) no conversion (areas already given as specific catchment area)", "(1) 1 / cell size (specific catchment area)", "(2) square root (catchment length)") - Area to Length Conversion. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
enum of ("(0) Moore et al. 1991", "(1) Desmet & Govers 1996", "(2) Boehner & Selige 2006") - Method (LS). Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
number - Rill/Interrill Erosivity. 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.
enum of ("(0) stable", "(1) instable (thawing)") - Stability. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
further parameters passed to qgisprocess::qgis_run_algorithm()
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.
logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.
logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
