|
x |
Integer, the simulation number |
D |
A numeric vector nsim long of sampled depletion |
SSB0 |
A numeric vector nsim long of total unfished spawning biomass |
nareas |
The number of spatial areas |
maxage |
The maximum age |
pyears |
The number of years to project forward. Equal to 'nyears' for optimizing for q. |
M_ageArray |
An array (dimensions nsim, maxage, nyears+proyears) with the natural mortality-at-age and year |
Mat_age |
An array (dimensions nsim, maxage, proyears+nyears) with the proportion mature for each age-class |
Asize |
A matrix (dimensions nsim, nareas) with size of each area |
Wt_age |
An array (dimensions nsim, maxage, nyears+proyears) with the weight-at-age and year |
FleetP |
A list of Fleets containing entries for V, retA, Find and Spat_targ |
mov |
An array (dimensions nsim, nareas, nareas) with the movement matrix |
SRrel |
A numeric vector nsim long specifying the recruitment curve to use |
hs |
A numeric vector nsim long with the steepness values for each simulation |
R0a |
A matrix (dimensions nsim, nareas) with the unfished recruitment by area |
SSBpR |
A matrix (dimensions nsim, nareas) with the unfished spawning-per-recruit by area |
aR |
A numeric vector nareas long with the Ricker SRR a values |
bR |
A numeric vector nareas long with the Ricker SRR b values |
bounds |
A numeric vector of length 2 with bounds for the optimizer |
maxF |
A numeric value specifying the maximum fishing mortality for any single age class |
useCPP |
logical - use the CPP code? For testing purposes only |
N |
Array of the numbers-at-age in population. Dimensions are nsim, maxage, nyears, nareas. Only values from the first year (i.e 'N[,,1,]') are used, which is the current N-at-age. |
MPA |
A matrix of spatial closures by year |
