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

QGIS algorithm Merge

Description

QGIS Algorithm provided by GDAL Merge (gdal:merge)

Usage

gdal_merge(
  INPUT = qgisprocess::qgis_default_value(),
  PCT = qgisprocess::qgis_default_value(),
  SEPARATE = qgisprocess::qgis_default_value(),
  NODATA_INPUT = qgisprocess::qgis_default_value(),
  NODATA_OUTPUT = qgisprocess::qgis_default_value(),
  OPTIONS = qgisprocess::qgis_default_value(),
  EXTRA = qgisprocess::qgis_default_value(),
  DATA_TYPE = qgisprocess::qgis_default_value(),
  OUTPUT = qgisprocess::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	multilayer - Input layers. .
PCT	boolean - Grab pseudocolor table from first layer. 1 for true/yes. 0 for false/no.
SEPARATE	boolean - Place each input file into a separate band. 1 for true/yes. 0 for false/no.
NODATA_INPUT	number - Input pixel value to treat as "nodata". A numeric value.
NODATA_OUTPUT	number - Assign specified "nodata" value to output. A numeric value.
OPTIONS	string - Additional creation options. String value.
EXTRA	string - Additional command-line parameters. String value.
DATA_TYPE	enum of ("Byte", "Int16", "UInt16", "UInt32", "Int32", "Float32", "Float64", "CInt16", "CInt32", "CFloat32", "CFloat64") - Output data type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
OUTPUT	rasterDestination - Merged. Path for new raster 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.
