Calculate effective recruitment multipliers from SR_mat

This helper compares realized recruitment stored in `SR_mat[, , "recruit"]` with recruitment predicted from `SR_type`, `a`, `b`, and `ssb`. It is useful for approximating a stochastic future projection with a deterministic mean trajectory while preserving the effective recruitment level used in the original projection.

get_sr_recruitment_multiplier(future_obj, years)

Arguments

future_obj

A future result object containing `SR_mat`.

years

Numeric or character vector of years to summarize.

Value

A tibble with one row per year and columns `year`, `mean_predicted_recruitment`, `mean_recruitment`, and `effective_recruitment_multiplier`.
