calculateEle141: Calculate Element 141 (Consumption)
In SWS-Methodology/faoswsAupus: Package to perform the AUPUS calculation.

Description Usage Arguments Details Value

This function computes element 141 (Consumption)

1	calculateEle141(stotal, data, aupusParam)

`stotal`	The column name of data corresponding to total supply.
`data`	The AUPUS node dataset, typically as produced by buildNodes.
`aupusParam`	A list of running parameters to be used in pulling the data. Typically, this is generated from getAupusParameter (see that function for a description of the required elements).

The following AUPUS logic is used in computing this element:

For commodity types in 58, 59, 60, and 61, element 141 is computed as E_11 + E_51 + E_61 - E_91 - E_95 - E_161.
For commodity type 50 (Jute), the original AUPUS logic was very complex and also written in such a way as to cause potential errors. Thus, no processing is done for this commodity type: it is left unchanged by this function.
For all other commodity types, the consumption is computed as a ratio of the total supply: E_141 = R_141 * (total supply) / 100

This function returns an integer vector containing the row numbers of observations which were updated. However, it also has a side effect: rows within the passed data.table ("data") have element 141's value and symbol updated.
