Extract Recruitment sigma
Description
Extract sigma R (recruitment variability) that was used in a model, as
indicated in the Dev$sigmaR
model component.
Usage
getSigmaR(model, digits=NULL)
Arguments
model |
fitted |
digits |
number of decimal places to use when rounding, or
|
Value
Vector of two numbers, representing recruitment variability in (1) the estimated age composition in the first year, and (2) subsequent annual recruitment.
Note
Thin wrapper to access model$Dev$sigmaR

Examples
getSigmaR(x.cod) # sigmaR used in assessment 0.5 and 1.0
estSigmaR(x.cod) # model estimates imply 0.20 and 0.52
getSigmaR(x.ling) # 0.6, deterministic age distribution in first year
estSigmaR(x.ling) # model estimates imply 0.36
getSigmaR(x.sbw)
estSigmaR(x.sbw) # large deviates in first year
plotN(x.sbw) # enormous plus group and 1991 cohort
# x.oreo assessment had deterministic recruitment, so no deviates
