# Projects

The goal of REDCapSync is to encapsulate a REDCap project into a standardized object. R6 gives a way of keeping some elements internal to the object. Behind-the-scenes is an R list where all of the metadata and data is stored.

    TEST_CLASSIC <- load_project(project_name = "TEST_CLASSIC")
    #> ✔ Loaded TEST_CLASSIC: '/Users/brandonrose/Library/CloudStorage/OneDrive-UniversityofTexasSouthwestern/Research/Test'
    listviewer::jsonedit(TEST_CLASSIC$.internal)

The R6 object contains those things behind-the-scenes but then uses several to build an environment. This allows `project$sync()` to update `project` without having to do `project <- project |> sync_something() |> another_function()`

    project <- load_project("TEST_CLASSIC")
    #> ✔ Loaded TEST_CLASSIC: '/Users/brandonrose/Library/CloudStorage/OneDrive-UniversityofTexasSouthwestern/Research/Test'
