qgis_rasterlayerhistogram: QGIS algorithm - Raster layer histogram

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

QGIS algorithm - Raster layer histogram

Description

QGIS Algorithm provided by QGIS Raster layer histogram (qgis:rasterlayerhistogram). This algorithm generates a histogram with the values of a raster layer. The raster layer must have a single band.

Usage

qgis_rasterlayerhistogram(
  INPUT = qgisprocess:::qgis_default_value(),
  BAND = qgisprocess:::qgis_default_value(),
  BINS = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	raster - Input layer. Path to a raster layer.
BAND	band - Band number. Integer value representing an existing raster band number.
BINS	number - number of bins. 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.
OUTPUT	fileDestination - Histogram. Path for new file.
...	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.
