Calculate recruitment from stock-recruit function

Usage

calc_recruitment(x, SRR = c("BH", "Ricker"), eq = FALSE, ...)

Arguments

x

Numeric, either the spawning output or the equilibrium spawners per recruit, from which the recruitment will be calculated. See argument eq.

SRR

Character to indicate the functional form of the stock recruit function

eq

Logical, indicates whether x is the spawning output (FALSE) or equilibrium spawners per recruit (TRUE)

...

Parameters of the SRR function. Provide one of two sets of variables:

  1. h, R0 and phi0, or

  2. a and b (alpha, beta values)

Examples

calc_recruitment(10, SRR = "Ricker", a = 2, b = 0.5)
#> [1] 0.1347589
calc_recruitment(10, SRR = "Ricker", h = 0.9, R0 = 1, phi0 = 1)
#> [1] 4.480838e-07
