Simulation Offsets

Offset the starting and ending times of the simulation, from the start and end time of the data used in calibration. This is used to override the default offsets of zero taken from the observed data passed to mp_tmb_calibrator.

Usage

mp_sim_offset(
  sim_start_offset,
  sim_end_offset,
  time_scale = "steps",
  time_column = "time"
)

Arguments

sim_start_offset

Number of time steps before the first data point to start each simulation.

sim_end_offset

Number of time steps after the last data point to end each simulation.

time_scale

Qualitative description of the size of a time step. The only valid values are 'steps' and 'daily'. If you would like each time step in the model to represent one day, then you should consider using 'daily'. Note that using 'daily' will require that your data represent time using a (1) Date vector, (2) character vector in YYYY-MM-DD format, or (3) integer vector that counts the number of days since some reference. Otherwise please choose 'steps', the default, and convert your time column into integer values that represent the time step that you would like in the model.

time_column

Name of the column that will identify the time at which particular values were observed.

Value

An object to be passed to the time argument of mp_tmb_calibrator.
