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

QGIS algorithm - Random terrain

Description

QGIS Algorithm provided by SAGA Next Gen Random terrain (sagang:randomterrain). —————- Arguments —————- RADIUS: Radius (cells) Default value: 25 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 ITERATIONS: Iterations 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 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 TARGET_OUT_GRID: Target Grid Argument type: rasterDestination Acceptable values: - Path for new raster layer

Usage

sagang_randomterrain(
  RADIUS = qgisprocess:::qgis_default_value(),
  ITERATIONS = 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(),
  TARGET_OUT_GRID = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

RADIUS	number - Radius (cells). 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.
ITERATIONS	number - Iterations. 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.
TARGET_OUT_GRID	rasterDestination - Target Grid. 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.
