Calculates the yield of a species for a range of fishing mortalities for that species while the fishing mortalities for the other species are held fixed.
Usage
plotYieldVsF(
params,
species,
F_range,
F_max = 1,
F_min = 0,
no_steps = 10,
distance_func = distanceSSLogN,
tol = 0.001,
t_max = 100
)
Arguments
- params
An object of class
MizerParams
.- species
Name of the target species
- F_range
A sequence of fishing mortalities at which to evaluate the yield. If missing, it is set to
seq(from = 0, to = F_max, length.out = no_steps)
.- F_max
The maximum fishing mortality. Used only if
F_range
is missing.- F_min
The minimum fishing mortality. Used only if
F_range
is missing.- no_steps
The number of steps to use. Only used if
F_range
is missing.- distance_func
A function that will be called after every
t_per
years with both the previous and the new state and that should return a number that in some sense measures the distance between the states. By default this uses the functiondistanceSSLogN()
that you can use as a model for your own distance function.- tol
The
projectToSteady
function stops when the relative change in the egg production RDI over t_per years is less than tol for every species.- t_max
The longest time to run project to find steady state.
