toolFillWithRegionAvg: Tool: FillWithRegionAvg

Description

This function fills missing values for countries with the (weighted) average of the respective region. The average is computed separately for every timestep. Currently only inputs with one data dimension are allowed as inputs. (If the filling should be performed over multiple data dimensions, call this function multiple times and bind the results together with magclass::mbind.)

Usage

toolFillWithRegionAvg(
  x,
  valueToReplace = NA,
  weight = NULL,
  callToolCountryFill = FALSE,
  regionmapping = NULL,
  verbose = TRUE,
  warningThreshold = 0.5,
  noteThreshold = 1
)

Value

A MAgPIE object with the missing values filled.

Arguments

x

MAgPIE object with country codes in the first and time steps in the second dimension.

valueToReplace

value that denotes missing data. Defaults to NA.

weight

MAgPIE object with weights for the weighted average. Must contain at least all the countries and years present in x. If no weights are specified, an unweighted average is performed.

callToolCountryFill

Boolean variable indicating whether the list of countries should first be filled to the official ISO code country list. Subsequently the newly added and previously missing values are filled with the region average.

regionmapping

Data frame containing the mapping between countries and regions. Expects column names CountryCode and RegionCode. Uses the currently set mapping if no mapping is specified.

verbose

Boolean variable indicating if the function should print out what it is doing. Can generate a lot of output for a large object.

warningThreshold

If more than this fraction of the countries in a given region and timestep have a missing value, throw a warning.

noteThreshold

If more than this fraction of the countries in a given region and timestep have a missing value, a note will be written.

Details

toolFillWithRegionAvg can be used in conjunction with toolCountryFill() to first fill up the list of countries to the official ISO code country list, and then fill values with the regional average (see callToolCountryFill Option).

Examples

x <- magclass::new.magpie(cells_and_regions = c("A", "B", "C", "D"), years = c(2000, 2005),
  fill = c(1, NA, 3, 4, 5, 6, NA, 8))
rel <- data.frame(CountryCode = c("A", "B", "C", "D"), RegionCode = c("R1", "R1", "R1", "R2"))
xfilled <- toolFillWithRegionAvg(x, regionmapping = rel)
