)raster - Grid. Path to a raster layer.
rasterDestination - Base Topographies. Path for new raster layer.
rasterDestination - Principal Components. Path for new raster layer.
vectorDestination - Eigen Vectors. Path for new vector layer.
number - Number of Components. 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.
boolean - Output of Base Topographies. 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.
boolean - Overwrite Previous Results. 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.
enum of ("(0) Square", "(1) Circle") - Kernel Type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
number - Kernel Radius. 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) correlation matrix", "(1) variance-covariance matrix", "(2) sums-of-squares-and-cross-products matrix") - Method. 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.
