Running rsimGmacs

• res<-runRsim.BBRKC()• res: list of lists

– mc: list object for model configuration• dims: list object with model dimensions info• params: list object with model parameters info

– mp: list object for model processes (rates)– mr: list object for model results

• R_yxz: recruitment by by y,x,z• iN_xmsz: initial abundance by x,m,s,z• N_yxmsz: 5-d array of population abundance by y,x,m,s,z• F_list: list of fisheries-related results• N_vyxmsz: 6-d array of abundance in surveys (v) by y,x,m,s,z
