QGIS algorithm - r.kappa — grass_r

QGIS Algorithm provided by GRASS r.kappa (grass:r.kappa). Calculate error matrix and kappa parameter for accuracy assessment of classification result.

grass_r_kappa(
  classification = qgisprocess:::qgis_default_value(),
  reference = qgisprocess:::qgis_default_value(),
  title = qgisprocess:::qgis_default_value(),
  .h = qgisprocess:::qgis_default_value(),
  .w = qgisprocess:::qgis_default_value(),
  output = qgisprocess:::qgis_default_value(),
  GRASS_REGION_PARAMETER = qgisprocess:::qgis_default_value(),
  GRASS_REGION_CELLSIZE_PARAMETER = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

classification: raster - Raster layer containing classification result. Path to a raster layer.
reference: raster - Raster layer containing reference classes. Path to a raster layer.
title: string - Title for error matrix and kappa. String 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.
.h: boolean - No header in the report. 1 for true/yes. 0 for false/no. 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. Original algorithm parameter name: -h.
.w: boolean - Wide report (132 columns). 1 for true/yes. 0 for false/no. 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. Original algorithm parameter name: -w.
output: fileDestination - Error matrix and kappa. Path for new file.
GRASS_REGION_PARAMETER: extent - GRASS GIS 7 region 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..
GRASS_REGION_CELLSIZE_PARAMETER: number - GRASS GIS 7 region cellsize (leave 0 for default). 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.
