grass_r_fill_stats: QGIS algorithm - r.fill.stats

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

QGIS algorithm - r.fill.stats

Description

QGIS Algorithm provided by GRASS r.fill.stats (grass:r.fill.stats). Rapidly fills 'no data' cells (NULLs) of a raster map with interpolated values (IDW).

Usage

grass_r_fill_stats(
  input = qgisprocess:::qgis_default_value(),
  .k = qgisprocess:::qgis_default_value(),
  mode = qgisprocess:::qgis_default_value(),
  .m = qgisprocess:::qgis_default_value(),
  distance = qgisprocess:::qgis_default_value(),
  minimum = qgisprocess:::qgis_default_value(),
  maximum = qgisprocess:::qgis_default_value(),
  power = qgisprocess:::qgis_default_value(),
  cells = qgisprocess:::qgis_default_value(),
  output = qgisprocess:::qgis_default_value(),
  uncertainty = qgisprocess:::qgis_default_value(),
  GRASS_REGION_PARAMETER = qgisprocess:::qgis_default_value(),
  GRASS_REGION_CELLSIZE_PARAMETER = qgisprocess:::qgis_default_value(),
  GRASS_RASTER_FORMAT_OPT = qgisprocess:::qgis_default_value(),
  GRASS_RASTER_FORMAT_META = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

input	raster - Input raster layer with data gaps to fill. Path to a raster layer.
.k	boolean - Preserve original cell values (By default original values are smoothed). 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: -k.
mode	enum of ⁠("wmean", "mean", "median", "mode")⁠ - Statistic for interpolated cell values. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
.m	boolean - Interpret distance as map units, not number of cells (Do not select with geodetic coordinates). 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: -m.
distance	number - Distance threshold (default: in cells) for interpolation. 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.
minimum	number - Minimum input data value to include in interpolation. 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.
maximum	number - Maximum input data value to include in interpolation. 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.
power	number - Power coefficient for IDW interpolation. 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.
cells	number - Minimum number of data cells within search 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.
output	rasterDestination - Output Map. Path for new raster layer.
uncertainty	rasterDestination - Uncertainty Map. Path for new raster layer.
GRASS_REGION_PARAMETER	extent - GRASS GIS 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 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.
GRASS_RASTER_FORMAT_OPT	string - Output Rasters format options (createopt). 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.
GRASS_RASTER_FORMAT_META	string - Output Rasters format metadata options (metaopt). 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.
...	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.
