QGIS Algorithm provided by QGIS (native c++) Promote to multipart (native:promotetomulti). This algorithm takes a vector layer with singlepart geometries and generates a new one in which all geometries are multipart. Input features which are already multipart features will remain unchanged. This algorithm can be used to force geometries to multipart types in order to be compatible with data providers with strict singlepart/multipart compatibility checks. See the 'Collect geometries' or 'Aggregate' algorithms for alternative options.

)source - Input layer. Path to a vector layer.
sink - Multiparts. Path for new vector layer.
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.
