TET: Calculates the Total Environ Throughflow for a Ecosystem Network Model

Description

Determines the total environ throughflow (TET) for each of the 2 x n environs of the selected network model. It returns both the TET calculated from a unit input (output) vector and from the observed or realized input (output) vector.

Usage

TET(x, balance.override = FALSE)

Arguments

x

A network object.

balance.override

Logical: should the function work if the model is not at steady-state?

Value

realized.input

vector of the n realized total environ throughflows for the n input oriented environs.

realzied.output

vector of the n realized total environ throughflows for the n ouptut oriented environs.

unit.input

vector of the n unit total environ throughflows for the n input oriented environs.

unit.output

vector of the n unit total environ throughflows for the n output oriented environs.
