##' @param LINES `vectorDestination` - Lines. Path for new vector layer.
##' @param POINTS `source` - Points. Path to a vector layer.
##' @param ORDER `field` - Order by.... The name of an existing field. ; delimited list of existing field names.
##' @param SEPARATE `field` - Separate by.... The name of an existing field. ; delimited list of existing field names.
##' @param ELEVATION `field` - Elevation. The name of an existing field. ; delimited list of existing field names.
##' @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`.
