Arguments

ELEVATION: raster - Elevation. Path to a raster layer.
CONVERGENCE: rasterDestination - Convergence Index. Path for new raster layer.
SLOPE: boolean - Gradient. 1 for true/yes. 0 for false/no. 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.
DIFFERENCE: enum of ("(0) direction to the center cell", "(1) center cell's aspect direction") - Difference. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
RADIUS: number - Radius (Cells). 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.
DW_WEIGHTING: enum of ("(0) no distance weighting", "(1) inverse distance to a power", "(2) exponential", "(3) gaussian") - Weighting Function. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
DW_IDW_POWER: number - Power. 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.
DW_BANDWIDTH: number - Bandwidth. 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.
...: 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.
