Reports quantities of commodity balance sheet items used for processing
and quantities of their corresponding processed output items.
get_processing_coefs(version = NULL)A tibble with the quantities for each processed product. It contains the following columns:
year: The year in which the recorded event occurred.
area_code: The code of the country where the data is from. For code
details see e.g. add_area_name().
item_cbs_code_to_process: FAOSTAT internal code for each one of the
items that are being processed and will give other subproduct items.
For code details see e.g. add_item_cbs_name().
value_to_process: tonnes of this item that are being processed. It
matches the amount found in the processing column from the data
obtained by get_wide_cbs().
item_cbs_code_processed: FAOSTAT internal code for each one of the
subproduct items that are obtained when processing. For code details
see e.g. add_item_cbs_name().
initial_conversion_factor: estimate for the number of tonnes of
item_cbs_code_processed obtained for each tonne of
item_cbs_code_to_process. It will be used to compute the
final_conversion_factor, which leaves everything balanced.
TODO: explain how it's computed.
initial_value_processed: first estimate for the number of tonnes of
item_cbs_code_processed obtained from item_cbs_code_to_process. It
is computed as value_to_process * initial_conversion_factor.
conversion_factor_scaling: computed scaling needed to adapt
initial_conversion_factor so as to get a final balanced total of
subproduct quantities. TODO: explain how it's computed.
final_conversion_factor: final used estimate for the number of tonnes of
item_cbs_code_processed obtained for each tonne of
item_cbs_code_to_process. It is computed as
initial_conversion_factor * conversion_factor_scaling.
final_value_processed: final estimate for the number of tonnes of
item_cbs_code_processed obtained from item_cbs_code_to_process. It
is computed as initial_value_processed * final_conversion_factor.
For the final data obtained, the quantities final_value_processed are
balanced in the following sense: the total sum of final_value_processed
for each unique tuple of (year, area_code, item_cbs_code_processed)
should be exactly the quantity reported for that year, country and
item_cbs_code_processed item in the production column obtained from
get_wide_cbs(). This is because they are not primary products, so the
amount from 'production' is actually the amount of subproduct obtained.
TODO: Fix few data where this doesn't hold.
File version to use as input. See whep_inputs for details.
# Note: These are smaller samples to show outputs, not the real data.
# For all data, call the function with default version (i.e. no arguments).
