In JanCaha/r_package_qgis: An extension of package "qgisprocess" providing direct R functions for QGIS functions

QGIS algorithm - Convert lines to polygons

Description

QGIS Algorithm provided by SAGA Next Gen Convert lines to polygons (sagang:convertlinestopolygons). —————- Arguments —————- POLYGONS: Polygons Argument type: vectorDestination Acceptable values: - Path for new vector layer LINES: Lines Argument type: source Acceptable values: - Path to a vector layer SINGLE: Create Single Multipart Polygon Default value: false Argument type: boolean Acceptable values: - 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 MERGE: Merge Line Parts to One Polygon Default value: false Argument type: boolean Acceptable values: - 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

Usage

sagang_convertlinestopolygons(
  POLYGONS = qgisprocess:::qgis_default_value(),
  LINES = qgisprocess:::qgis_default_value(),
  SINGLE = qgisprocess:::qgis_default_value(),
  MERGE = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

POLYGONS	vectorDestination - Polygons. Path for new vector layer.
LINES	source - Lines. Path to a vector layer.
SINGLE	boolean - Create Single Multipart Polygon. 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.
MERGE	boolean - Merge Line Parts to One Polygon. 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()
.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.
.quiet	logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.
.messages	logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
