An R package to work with the Generalized Model for Assessing Crustacean Stocks (GMACS)

gmr is an R package providing tools to work with GMACS, a generalized size-structured assessment model for Crustaceans. Specifically, it includes an extensive library of functions developed to build and run GMACS for one or several crustacean stock(s) and to plot outputs of the model.

To install the gmr package, the devtools and gdata packages are required.

    if(!require("devtools"))
        install.packages("devtools")
    if(!require("devtools"))
        install.packages("gdata")

    # Install development version from Github
    .DirSrc <- "GMACS-project/gmr"
    devtools::install_github(.DirSrc)

Now you can load the package and inspect the functions:

    # Load the gmr package
    library(gmr)
    # Explore function
    plot_growth

Using the functions requires output from the General Model for Assessing Crustacean Stocks (GMACS) which is described in the GMACS repo.
