This is used to use the results from one simulation as the starting values for another simulation.
Arguments
- params
A
MizerParams()object- sim
A
MizerSimobject.- time_range
The time range (either a vector of values, a vector of min and max time, or a single value) to average the abundances over. Default is the final time step.
Value
The params object with updated initial values and initial effort.
Because of the way the
R language works, setInitialValues() does not make the changes to the
params object that you pass to it but instead returns a new params object.
So to affect the change you call the function in the form
params <- setInitialValues(params, sim).
Details
The initial abundances (for both species and resource) in the params
object are set to the abundances in a MizerSim object, averaged over
a range of times. Similarly, the initial effort in the params object is
set to the effort in the MizerSim object, again averaged over that range
of times.
When no time range is specified, the initial values are taken from the final
time step of the simulation.
