The fishgrowbot
package provides a tool to conduct back-calculation
based on otolith readings and fit the von Bertalanffy growth curve with
a hierarchical structure, both in a Bayesian framework.
It contains:
-
A function
bcalc()
to perform the back-calculations which yields length-at-age estimations with measures of uncertainty. -
A function called
growthreg()
to fit the von Bertalanffy growth model. -
Functions to visualize results.
fishgrowbot
uses Markov Chain Monte Carlo simulations provided by
stan.
Therefore, the first step is to install
stan.
The best way to install the latest version of fishgrowbot
is to
install it from GitHub.
install.packages("devtools")
devtools::install_github("nschiett/fishgrowbot", dependencies = TRUE)
library(fishgrowbot)
