Description Usage Format Details

This dataset provides each of the individual item codes/names for all the commodities and also specifies whether that particular commodity is a target commodity (i.e. is aggregated up to in the standardization) as well as the equivalent FBS code.

1	data(itemTree)

A data.table object of 12 columns by 808 rows.

A short description of each column is below:

itemCode: The Supply and Utilization Account (SUA) ID number for the commodity.
itemName: The name of the commodity
incTot: (More documentation needed here...)
aggCom: (More documentation needed here...)
weight: (More documentation needed here...)
target: Specifies if the particular commodity is a target. If so, then all the children of this commodity will be aggregated up to this commodity (i.e. expressed in this commodity) during the standardization proceedure.
convType: If this column takes the value "(cal.)", then it is standardized only for caloric purposes. For example, when wheat (15) is processed, it generates flour wheat (16), bran wheat (17), and germ wheat (19). If each of these items is standardized to wheat in terms of quantities, we'll be overcounting. However, calories can be standardized, and so one commodity is chosen for the quantity standardization (in this case flour wheat) and all three are used for caloric standardization. The (cal.) indicates which commodities are not standardized with quantities but only with calories.
targetCode: Each commodity is standardized to some commodity (possibly itself). The targetCode specifies the itemCode of the "target", or the commodity it is standardized to.
targetName: The name of the target commodity, see targetCode.
baseExtraction:
fbsCode: The corresponding code for this commodity in the Food Balance Sheets (FBS).
fbsName: The corresponding name for this commodity in the Food Balance Sheets (FBS).
