sagang_zonalrasterstatistics: QGIS algorithm - Zonal raster statistics

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

QGIS algorithm - Zonal raster statistics

Description

QGIS Algorithm provided by SAGA Next Gen Zonal raster statistics (sagang:zonalrasterstatistics). —————- Arguments —————- ZONES: Zone Grid Argument type: raster Acceptable values: - Path to a raster layer CATLIST: Categorical Grids (optional) Argument type: multilayer STATLIST: Grids to analyse (optional) Argument type: multilayer ASPECT: Aspect (optional) Argument type: raster Acceptable values: - Path to a raster layer OUTTAB: Zonal Statistics Argument type: vectorDestination Acceptable values: - Path for new vector layer SHORTNAMES: Short Field Names Default value: true Argument type: boolean Acceptable values: - 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

Usage

sagang_zonalrasterstatistics(
  ZONES = qgisprocess:::qgis_default_value(),
  CATLIST = qgisprocess:::qgis_default_value(),
  STATLIST = qgisprocess:::qgis_default_value(),
  ASPECT = qgisprocess:::qgis_default_value(),
  OUTTAB = qgisprocess:::qgis_default_value(),
  SHORTNAMES = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

ZONES	raster - Zone Grid. Path to a raster layer.
CATLIST	multilayer - Categorical Grids. .
STATLIST	multilayer - Grids to analyse. .
ASPECT	raster - Aspect. Path to a raster layer.
OUTTAB	vectorDestination - Zonal Statistics. Path for new vector layer.
SHORTNAMES	boolean - Short Field Names. 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.
...	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.
