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

interface with other get*
and est*
functions.

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
