...The author (Dean Attali) collected many of the “harder” or less-documented tricks he uses or encounters frequently—things like controlling UI behavior dynamically, managing reactive logic, optimizing interactivity, and structuring large Shiny codebases. The repo’s structure includes folders of example apps each implementing a specific trick or pattern (e.g. loading spinners, dynamic UI, hiding/showing UI elements, handling file uploads, URL parameter inputs). Each example is runnable so developers can inspect code and behavior side-by-side. The README acts as a “table of contents” linking to example apps and the contexts in which they are useful (beginner, intermediate, advanced).

tidyverse is a meta‑package that installs and loads a cohesive suite of R packages designed for data science, sharing underlying design principles, grammar, and data structures. Core components include ggplot2, dplyr, tidyr, readr, purrr, tibble, stringr, forcats, and more. It promotes tidy data workflows and consistency across tasks.
