- Spawners
A vector of the number of the spawners (x-axis).

- expectedR
A vector of the expected recruitment (from the stock-recruit function) corresponding to values of

`Spawners`

.- R0
Virgin recruitment.

- S0
Virgin spawners.

- rec_dev
If recruitment deviations are estimated, a vector of estimated recruitment (in normal space) corresponding to values of

`Spawners`

.- trajectory
Indicates whether arrows will be drawn showing the trajectory of spawners and recruitment deviations over time.

- y_zoom
If recruitment deviations are plotted, the y-axis limit relative to maximum expected recruitment

`expectedR`

. If`NULL`

, all recruitment values are plotted.- ylab
Character string for label on y-axis.
