)

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.
