best F

Source: R/best_f.R

Use this year's model to recalculate the F for the previous year that would have produced the specified OFL for the previous year

best_f(data, m, last_ofl, type = 1, f_ratio = NULL, m2 = NULL)

Arguments

data

data.frame in form (age, naa, waa, saa)
m

natural mortality (for both sexes(type=1) or for sex 1 (type=2 or type=3 estimates))
last_ofl

OFL from the previous assessment
type

1 = 1 sex - 1 gear; 2 = 1 sex - 2 gear; 3 = 2 sex - 1 gear - 2m; 4 = 2 sex - 2 gear - 2m
f_ratio

is the final ratio of catch between gears in the previous year, as estimated by this year's model - only needed if using multiple gear types
m2

is the second estimate of natural mortality

Value

The estimated F_OFL
