Calculates the derivative for a single time step and saves the output

rsim.deriv(Rsim.scenario, sim.year = 0, sim.month = 0, tstep = 0)

Arguments

Rsim.scenario

Scenario object that contains all of the rsim rates and forcing functions generated by rsim.scenario.

sim.year

Will inherit from apply functions

sim.month

Will inherit from apply functions

tstep

Sub-monthly time step usually set to 0.
