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")
#> ! No cached projects... use `setup_project(...)`
#> ✔ Loaded TEST project TEST_CLASSIC!
#> ! Does not actually communicate with any REDCap API
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")
#> ! No cached projects... use `setup_project(...)`
#> ✔ Loaded TEST project TEST_CLASSIC!
#> ! Does not actually communicate with any REDCap API
# projects have read-only active bindings
