calculateEle93: Calculate Element 93

In SWS-Methodology/faoswsAupus: Package to perform the AUPUS calculation.

Description

This function calculates element 93 (outflow unit value). The logic is very similar to the calculation for element 63 (inflow unit value) in that unit value (93) should be the total value (92) divided by the total quantity (91). Also, the multiplicative constant of 1000 is still used in this case, so the formula is 93 = 92 * 1000 / 91.

Usage

calculateEle93(data, aupusParam)

Arguments

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).

Details

However, there is one difference between computation of element 93 and element 63: computation is not done for elements 42 through 52.

Value

This function returns a list (of length 2) of integer vectors containing the row numbers of observations which were updated (the first vector when a value was computed, the second for when 62 or 61 was missing). However, it also has a side effect: rows within the passed data.table ("data") have element 63's value and symbol updated.
