##' @param points `source` - Name of existing vector map with points. Path to a vector layer.
##' @param areas `source` - Name of existing vector map with areas. Path to a vector layer.
##' @param type `enum` of `("point", "centroid")` - Input feature type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param method `enum` of `("sum", "average", "median", "mode", "minimum", "min_cat", "maximum", "max_cat", "range", "stddev", "variance", "diversity")` - Method for aggregate statistics. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param points_column `field` - Column name of points map to use for statistics. The name of an existing field. ; delimited list of existing field names.
##' @param count_column `string` - Column name to upload points count (integer, created if doesn't exists). 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.
##' @param stats_column `string` - Column name to upload statistics (double, created if doesn't exists). 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.
##' @param output `vectorDestination` - Updated. Path for new vector layer.
##' @param GRASS_REGION_PARAMETER `extent` - GRASS GIS 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..
##' @param GRASS_SNAP_TOLERANCE_PARAMETER `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.
##' @param GRASS_MIN_AREA_PARAMETER `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.
##' @param GRASS_OUTPUT_TYPE_PARAMETER `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'.
##' @param GRASS_VECTOR_DSCO `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.
##' @param GRASS_VECTOR_LCO `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.
##' @param GRASS_VECTOR_EXPORT_NOCAT `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.
##' @param ... further parameters passed to `qgisprocess::qgis_run_algorithm()`
##' @param .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`.
##' @param .quiet logical specifying if parameter `.quiet` for `qgisprocess::qgis_run_algorithm()` Default value is `TRUE`.
##' @param .messages logical specifying if messages from `qgisprocess::qgis_run_algorithm()` should be printed (`TRUE`) or not (`FALSE`). Default value is `FALSE`.
