QGIS algorithm - Random field

Description

QGIS Algorithm provided by SAGA Next Gen Random field (sagang:randomfield). —————- Arguments —————- METHOD: Method Default value: 1 Argument type: enum Available values: - 0: (0) Uniform - 1: (1) Gaussian Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' MEAN: Arithmetic Mean Default value: 0 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 STDDEV: Standard Deviation 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 TARGET_USER_XMIN TARGET_USER_XMAX TARGET_USER_YMIN TARGET_USER_YMAX: Output extent (optional) Argument type: extent Acceptable values: - A comma delimited string of x min, x max, y min, y max. E.g. '4,10,101,105' - Path to a layer. The extent of the layer is used. TARGET_USER_SIZE: Cellsize Default value: 100 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 OUT_GRID: Random Field Argument type: rasterDestination Acceptable values: - Path for new raster layer

Usage

sagang_randomfield(
  METHOD = qgisprocess:::qgis_default_value(),
  MEAN = qgisprocess:::qgis_default_value(),
  STDDEV = qgisprocess:::qgis_default_value(),
  TARGET_USER_XMIN_TARGET_USER_XMAX_TARGET_USER_YMIN_TARGET_USER_YMAX =
    qgisprocess:::qgis_default_value(),
  TARGET_USER_SIZE = qgisprocess:::qgis_default_value(),
  OUT_GRID = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

METHOD	enum of ⁠("(0) Uniform", "(1) Gaussian")⁠ - Method. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
MEAN	number - Arithmetic Mean. 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.
STDDEV	number - Standard Deviation. 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.
TARGET_USER_XMIN_TARGET_USER_XMAX_TARGET_USER_YMIN_TARGET_USER_YMAX	extent - Output extent. A comma delimited string of x min, x max, y min, y max. E.g. '4,10,101,105'. Path to a layer. The extent of the layer is used.. Original algorithm parameter name: TARGET_USER_XMIN TARGET_USER_XMAX TARGET_USER_YMIN TARGET_USER_YMAX.
TARGET_USER_SIZE	number - Cellsize. 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.
OUT_GRID	rasterDestination - Random Field. 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.
