)source - 'from' vector map. Path to a vector layer.
enum of ("point", "line", "boundary", "area", "centroid") - 'from' feature type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
source - 'to' vector map. Path to a vector layer.
enum of ("point", "line", "boundary", "area", "centroid") - 'to' feature type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
number - Maximum distance or -1.0 for no limit. 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.
number - Minimum distance or -1.0 for no limit. 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 ("cat", "dist", "to_x", "to_y", "to_along", "to_angle", "to_attr") - 'upload': Values describing the relation between two nearest features. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
field - Column name(s) where values specified by 'upload' option will be uploaded. The name of an existing field. ; delimited list of existing field names.
field - Column name of nearest feature (used with upload=to_attr). The name of an existing field. ; delimited list of existing field names.
vectorDestination - Nearest. Path for new vector layer.
vectorDestination - Distance. Path for new vector layer.
extent - GRASS GIS 7 region extent. A comma delimited string of x min, x max, y min, y max. E.g. '4,10,101,105'. Path to a layer. The extent of the layer is used..
number - v.in.ogr snap tolerance (-1 = no snap). 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.
number - v.in.ogr min area. 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 ("auto", "point", "line", "area") - v.out.ogr output type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
string - v.out.ogr output data source options (dsco). String 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.
string - v.out.ogr output layer options (lco). String 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 - Also export features without category (not labeled). Otherwise only features with category are exported. 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.
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.
