leslie_r: leslie_r()

In Henning-Winker/SPMpriors: SPM prior generation with FishLife

Description

Generate r from Leslie Matrix assuming BevHolt SSR (Afte MacAllister)

Usage

leslie_r(
  Loo = 80,
  K = 0.2,
  t0 = -0.5,
  aW = 0.01,
  bW = 3.04,
  mat = c(35, 0),
  dmat = NULL,
  minage = 0,
  maxage = 12,
  M = 0.25,
  h = 0.7
)

Arguments

Loo	infinitive length (cm)
K	brody growth coefficient K
t0	theoretical age a length zero (default -0.5)
aW	parameter of the lenght-weight relation (default 0.01)
bW	parameter of the lenght-weight relation (default 3.04)
mat	length- c(Length,0) or age-at-50-maturity c(Age,1) (default is length, i.e. c(Lenght,0))
dmat	width of ogive (default=0.1*Mat)
M	natural mortality
h	steepness of BevHolt SSR
tmin	minimum age
tmax	maximum age

Value

r, G (generation time)
