In this tutorial we'll make a couple of simple apps to get you started.

Prerequisites

1. Shiny - install.packages("shiny")
2. Tidyverse - install.packages("tidyverse")
3. Palmer Penguins - install.packages("palmerpenguins")
4. rsconnect - install.packages("rsconnect")

We will walk through the following apps

App 1

Boilerplate Shiny App (comes with Shiny) that builds a simple web app using Old Faithful Geyser in Yellowstone National Park(faithful) data. We'll use this to understand the structure of a Shiny App.

App 2

Build a simple Shiny App that prints out exactly what you type in. Also introduces you to putting HTML elements in a Shiny app.

App 3

A shiny app that can be used for basic exploratory data analysis. Uses the Palmer Penguins dataset (palmerpenguins)
