qgis_retainfields: QGIS algorithm - Retain fields

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

QGIS algorithm - Retain fields

Description

QGIS Algorithm provided by QGIS (native c++) Retain fields (native:retainfields). Retains selected fields from a vector layer. This algorithm takes a vector layer and generates a new one that retains only the selected fields. All other fields will be dropped.

Usage

qgis_retainfields(
  INPUT = qgisprocess:::qgis_default_value(),
  FIELDS = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	source - Input layer. Path to a vector layer.
FIELDS	field - Fields to retain. The name of an existing field. ; delimited list of existing field names.
OUTPUT	sink - Retained fields. Path for new vector layer.
...	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.
