Run back-calculation in Bayesian framework

bcalc(data, ...)

Arguments

data

data	`data.frame` containing results from otolith reading plus information on the length of hatching (column `l0p`) of a certain species. Data should contain: id: unique fish id per individual. radi: measurements of otolith growth rings (in mm). agei: age estimation of fish. lencap: length at capture (in mm). radcap: radius of otolith at capture (in mm). l0p: length of fish at hatching (in mm).
...	arguments to add to `sampling`.

data.frame containing results from otolith reading plus information on the length of hatching (column l0p) of a certain species. Data should contain:

id: unique fish id per individual.
radi: measurements of otolith growth rings (in mm).
agei: age estimation of fish.
lencap: length at capture (in mm).
radcap: radius of otolith at capture (in mm).
l0p: length of fish at hatching (in mm).

arguments to add to sampling.

Details

Returns a list of model fit and a dataset called lengths with the estimated lengths at age:

l_m: mean length in mm.
l_sd: sd of length.
l_lb: lower 95% CI quantile.
l_ub: upper 95% CI quantile.

Input data should include radi at age 0 measurements as well, but can handle missing data (NA) for the cases where it is not possible to measure the radius at hatching.
