sagang_simpsonindex: QGIS algorithm - Simpson index

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

QGIS algorithm - Simpson index

Description

QGIS Algorithm provided by SAGA Next Gen Simpson index (sagang:simpsonindex). —————- Arguments —————- CATEGORIES: Categories Argument type: raster Acceptable values: - Path to a raster layer COUNT: Number of Categories Argument type: rasterDestination Acceptable values: - Path for new raster layer INDEX: Simpson Index Argument type: rasterDestination Acceptable values: - Path for new raster layer KERNEL_TYPE: Kernel Type Default value: 1 Argument type: enum Available values: - 0: (0) Square - 1: (1) Circle Acceptable values: - Number of selected option, e.g. '1' - Comma separated list of options, e.g. '1,3' KERNEL_RADIUS: Radius Default value: 2 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_simpsonindex(
  CATEGORIES = qgisprocess:::qgis_default_value(),
  COUNT = qgisprocess:::qgis_default_value(),
  INDEX = qgisprocess:::qgis_default_value(),
  KERNEL_TYPE = qgisprocess:::qgis_default_value(),
  KERNEL_RADIUS = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

CATEGORIES	raster - Categories. Path to a raster layer.
COUNT	rasterDestination - Number of Categories. Path for new raster layer.
INDEX	rasterDestination - Simpson Index. Path for new raster layer.
KERNEL_TYPE	enum of ⁠("(0) Square", "(1) Circle")⁠ - Kernel Type. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
KERNEL_RADIUS	number - Radius. 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.
