R/grass_r_series.R

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

##' QGIS Algorithm provided by GRASS r.series (grass:r.series). Makes each output cell value a function of the values assigned to the corresponding cells in the input raster layers. Input rasters layers/bands must be separated in different data sources.
##'
##' @title QGIS algorithm - r.series
##'
##' @param input `multilayer` - Input raster layer(s). .
##' @param .n `boolean` - Propagate NULLs. 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: -n.
##' @param method `enum`  of `("average", "count", "median", "mode", "minimum", "min_raster", "maximum", "max_raster", "stddev", "range", "sum", "variance", "diversity", "slope", "offset", "detcoeff", "quart1", "quart3", "perc90", "skewness", "kurtosis", "quantile", "tvalue")` - Aggregate operation. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param quantile `string` - Quantile to calculate for method=quantile. 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.
##' @param weights `string` - Weighting factor for each input map, default value is 1.0. 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.
##' @param range `range` - Ignore values outside this range (lo,hi). Two comma separated numeric values, e.g. '1,10'.
##' @param output `rasterDestination` - Aggregated. Path for new raster layer.
##' @param 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..
##' @param 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.
##' @param 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.
##' @param 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.
##' @param ... further parameters passed to `qgisprocess::qgis_run_algorithm()`
##' @param .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`.
##' @param .quiet logical specifying if parameter `.quiet` for `qgisprocess::qgis_run_algorithm()` Default value is `TRUE`.
##' @param .messages logical specifying if messages from `qgisprocess::qgis_run_algorithm()` should be printed (`TRUE`) or not (`FALSE`). Default value is `FALSE`.
