Measure distance between current and previous state in terms of fish abundances
Source:R/steady.R
distanceSSLogN.Rd
Calculates the sum squared difference between log(N) in current and previous
state. This function can be used in projectToSteady()
to decide when
sufficient convergence to steady state has been achieved.
Arguments

- current
A named list with entries
n

Value
The sum of squares of the difference in the logs of the (nonzero)
fish abundances n:
sum((log(current$n) - log(previous$n))^2)
