Defines functions grass_r_series_accumulate

Documented in grass_r_series_accumulate

##' QGIS Algorithm provided by GRASS r.series.accumulate (grass:r.series.accumulate). Makes each output cell value an accumulation function of the values assigned to the corresponding cells in the input raster map layers.
##'
##' @title QGIS algorithm - r.series.accumulate
##'
##' @param input `multilayer` - Input raster layer(s). .
##' @param lower `raster` - Raster map specifying the lower accumulation limit. Path to a raster layer.
##' @param upper `raster` - Raster map specifying the upper accumulation limit. Path to a raster layer.
##' @param method `enum`  of `("gdd", "bedd", "huglin", "mean")` - This method will be applied to compute the accumulative values from the input maps. Number of selected option, e.g. '1'. Comma separated list of options, e.g. '1,3'.
##' @param scale `number` - Scale factor for input. 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 shift `number` - Shift factor for input. 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 range `range` - Ignore values outside this range (min,max). Two comma separated numeric values, e.g. '1,10'.
##' @param limits `range` - Lower and upper accumulation limits (lower,upper). Two comma separated numeric values, e.g. '1,10'.
##' @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 .f `boolean` - Create a FCELL map (floating point single precision) as output. 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: -f.
##' @param output `rasterDestination` - Accumulated. 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`.
