sequence: Sequence of scenarios

Description

A sequence of scenarios is treated as a single scenario and each scenario is simulated one after the other. If scenario n in a sequence was simulated, scenario n+1 will start off in the model state where n had ended. Scenario sequences can be used to e.g. implement changes in model parameters over time.

Value

an S4 object of type ScenarioSequence

Details

Requirements

All scenarios in a sequence must fulfill the following requirements:

• All scenarios must have identical state variables

• The output times of all scenarios must represent a continuous time series without gaps or overlaps

Limitations

Only simulation of sequences are supported, at the moment. Effects and effect profiles (EPx values) cannot be derived, yet.

Examples

# create two scenarios that need to be simulated one after the other
scen1 <- minnow_it %>% set_times(0:3)
scen2 <- minnow_it %>% set_times(3:6) %>% set_param(c(kd=0))

# create a sequence and assign scenarios
sq <- sequence(list(scen1, scen2))

# simulate the sequence

simulate(sq)
