scenario_bau filters for values between start_year and end_year for bau_scenario and returns values in value. If values are missing for years between start_year and end_year, the last available value will be imputed.

Usage

scenario_bau(
  df,
  only_reported_estimated = FALSE,
  value_col = "value",
  start_year = 2018,
  end_year = 2025,
  scenario_name = glue::glue("business_as_usual"),
  scenario_col = "scenario",
  avoid_worstening = FALSE,
  trim = TRUE,
  small_is_best = FALSE,
  keep_better_values = TRUE,
  upper_limit = 100,
  lower_limit = 0,
  trim_years = TRUE,
  start_year_trim = start_year,
  end_year_trim = end_year,
  ind_ids = billion_ind_codes("all"),
  bau_scenario = "historical",
  default_scenario = "default"
)

Arguments

df

Data frame in long format, where 1 row corresponds to a specific country, year, and indicator.

only_reported_estimated

(logical) if TRUE only the last reported and estimated values are imputed.

value_col

Column name of column with indicator values.

start_year

Start year for scenario, defaults to 2018.

end_year

End year for scenario, defaults to 2025

scenario_name

Name of the scenario. Defaults to scenario_percent_change_baseline_year

scenario_col

Column name of column with scenario identifiers. Useful for calculating contributions on data in long format rather than wide format.

avoid_worstening

If TRUE, the value at start_year is kept if it is better (see small_is_best).

trim

logical to indicate if the data should be trimmed between upper_limit and lower_limit.

small_is_best

Logical to identify if a lower value is better than a higher one (e.g. lower obesity in a positive public health outcome, so obesity rate should have small_is_best = TRUE).

keep_better_values

logical to indicate if "better" values should be kept from value_col if they are present. Follows the direction set in small_is_best. For instance, if small_is_best is TRUE, then value_col lower than col will be kept.

upper_limit

limit at which the indicator should be caped. Can take any of "guess", or any numeric. guess (default) will take 100 as the limit if percent_change is positive, and 0 if negative.

lower_limit

limit at which the indicator should be caped. Can take any of "guess", or 0 to 100. guess (default) will take 0 as the limit if percent_change is positive, and 100 if negative.

trim_years

logical to indicate if years before start_year_trim and after end_year_trim should be removed

start_year_trim

(integer) year to start trimming from.

end_year_trim

(integer) year to end trimming.

ind_ids

Named vector of indicator codes for input indicators to the Billion. Although separate indicator codes can be used than the standard, they must be supplied as a named vector where the names correspond to the output of billion_ind_codes().

bau_scenario

name of scenario to be used for business as usual. Default is historical.

default_scenario

name of the default scenario to be used.
