A internal function that optimizes for F/M when SPR is provided in the simulation parameters.
getFMfun(FM, LB_pars, Control = list())a F/M value
an object of class 'LB_pars' that contains the life history information
a list of control options for the LBSPR model.
sum of squares value
The Control options are:
modtypeModel Type: either Growth-Type-Group Model (default: "GTG") or Age-Structured ("absel")
maxsdMaximum number of standard deviations for length-at-age distribution (default is 2)
ngtgNumber of groups for the GTG model. Default is 13
PProportion of survival of initial cohort for maximum age for Age-Structured model. Default is 0.01
NageNumber of pseudo-age classes in the Age Structured model. Default is 101
maxFMMaximum value for F/M. Estimated values higher than this are trunctated to maxFM. Default is 4
