shinymisc: Miscellaneous educational shiny apps

The shinymisc package provides a set of apps that are useful for beginner, intermediate, and advanced shiny developers to explore different features of the shiny framework and philosophy.

Installation

devtools::install_github("Nelson-Gon/shinymisc")

Loading the package

library(shinymisc)

Exploring included apps

shinymisc contains a number of apps that demonstrate different concepts.

To view an app, run the following:

run_app(app_name = "theming")

• Plot theming

This app takes a fairly advanced approach at demonstrating how one can combine different shiny principles to achieve plot customization. This was built to help me figure out how to best choose themes from different packages. In particular, I wanted to do this even if the package was not on the search list.

This app explores concepts of reactivity, modularization, testing, and scaling in general.

run_app("theming")

• Sample App

This app aims to do something fairly simple. It takes input data, allows user confirmation and finally prints the data entered. It was built as part of a blog I wrote to highlight shiny features like reactivity, observers, and performance improvements. This blog post is available at https://nelson-gon.github.io/12/12/2021/shiny-reactivity/. You can view the source code here.

• List Package Functions

This app was written as I tried to play around with namespaces and accessing functions in a package. In particular, I wanted to be able to load a function from a package without necessarily loading said package first. This is important because sometimes loading a package may result in function conflicts causing further debugging work.

• Shiny Modules

This simple app explores the use of shiny modules. This is aimed at demonstrating how one can reuse code across different places within the app without copying and pasting the same code over and over again. The app also shows how to use some different layouts.

• More Modules

Another module based app that also includes some basic plotly plots. This app was created as a way for me to debug some issue with shiny's module system and the use of update* functions. Specifically, sometimes, it is possible that update* functions may not work as expected/intended. Unfortunately this is not readily visible in this app. Hopefully with more exploration, one could meet this pitfall and play with ways around it.

Keep building,

Nelson
