A collection of R functions for use with Stock Synthesis, a
    fisheries stock assessment modeling platform written in ADMB by Dr. Richard
    D. Methot at the NOAA Northwest Fisheries Science Center. The functions
    include tools for summarizing and plotting results, manipulating files,
    visualizing model parameterizations, and various other common stock
    assessment tasks.
    This version of '{r4ss}' is compatible with Stock Synthesis versions
    3.24 through 3.30 (specifically version 3.30.19.01, from April
    2022).

Rapid realistic routing on multimodal transport networks
    (walk, bike, public transport and car) using 'R5', the Rapid Realistic
    Routing on Real-world and Reimagined networks engine
    <https://github.com/conveyal/r5>. The package allows users to generate
    detailed routing analysis or calculate travel time and monetary cost matrices 
    using seamless parallel computing on top of the R5 Java machine.  While R5
    is developed by Conveyal, the package r5r is independently developed
    by a team at the Institute for Applied Economic Research (Ipea) with
    contributions from collaborators. Apart from the documentation in this
    package, users will find additional information on R5 documentation at
    <https://docs.conveyal.com/>. Although we try to keep new releases of
    r5r in synchrony with R5, the development of R5 follows Conveyal's
    independent update process. Hence, users should confirm the R5 version
    implied by the Conveyal user manual (see
    <https://docs.conveyal.com/changelog>) corresponds with the R5 version
    that r5r depends on. This version of r5r depends on R5 v7.1.

Interactively build and explore public transit routes with
    'r5r' package via a graphical user interface in a 'shiny' app. The
    underlying routing methods are described in Pereira et al. (2021)
    <doi:10.32866/001c.21262>.

Creates classes with reference semantics, similar to R's
    built-in reference classes. Compared to reference classes, R6 classes
    are simpler and lighter-weight, and they are not built on S4 classes
    so they do not require the methods package. These classes allow public
    and private members, and they support inheritance, even when the
    classes are defined in different packages.
