)Arguments
- logF
log fishing mortality
- M_at_Age
Vector of M-at-age
- Wt_at_Age
Vector of weight-at-age
- Mat_at_Age
Vector of maturity-at-age
- Fec_at_Age
Vector of mature weight-at-age
- V_at_Age
Vector of selectivity-at-age
- maxage
Maximum age
- relRfun
Optional. A function used to calculate reference points if
SRrelc =3- SRRpars
Optional. A named list of arguments for
SRRfun- R0x
R0 for this simulation. Set = 1 if SRrelx = 4 for per-recruit calculations
- SRrelx
SRR type for this simulation. Use 4 for per-recruit calculations, i.e. constant recruitment.
- hx
numeric. Steepness value for this simulation. Not used if SRrelx = 4.
- SSBpR
numeric. Unfished spawners per recruit for this simulation. Not used if SRrelx = 4.
- opt
Option. 1 = return -Yield, 2= return all MSY calcs
- plusgroup
Integer. Default = 0 = no plus-group. Use 1 to include a plus-group
- spawn_time_frac
Numeric. Fraction of the year when spawning occurs. Default = 0.
