sagang_invertdatanodata: QGIS algorithm - Invert data/no-data

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

QGIS algorithm - Invert data/no-data

Description

QGIS Algorithm provided by SAGA Next Gen Invert data/no-data (sagang:invertdatanodata). —————- Arguments —————- INPUT: Grid Argument type: raster Acceptable values: - Path to a raster layer OUTPUT: Result Argument type: rasterDestination Acceptable values: - Path for new raster layer VALUE: Data Value Default value: 1 Argument type: number Acceptable values: - 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

Usage

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

Arguments

INPUT	raster - Grid. Path to a raster layer.
OUTPUT	rasterDestination - Result. Path for new raster layer.
VALUE	number - Data Value. 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.
...	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.
