Shiny Tutorial

This shiny tutorial uses {learnr} package to create an interactive tutorial. The tutorial is designed to help you learn the basics of shiny within a shiny application.

Getting started

1. Clone this repository and open the shiny-tutorial.Rproj file in RStudio.
2. To install all necessary packages, run the following command in R:

paks <- c("learnr", "rmarkdown", "DT")
install.packages(paks)

3. Open the shiny_tutorial/shiny_tutorial.Rmd
4. Execute the shiny tutorial using the button Run the document
5. Follow the steps and complete the exercises

Run the tutorial alongside your shiny project

To be able to develop a shiny application alongside an active shiny tutorial, 2 options are available:

• run the tutorial in the background locally
• run the tutorial on binder

Run the tutorial in the background locally

You need to follow some extra-steps:

1. Stop and close any previous shiny tutorial that is running
2. Create a new shiny project within RStudio

• File -> New File -> Shiny Web App -> Multiple File

3. In the newly created shiny project, go to Background jobs tab and click on Start background job to create a new background job
4. Select run_in_background.R R script on clicking the Browse button
5. Select the shiny-tutorial folder as the working directory on clicking the Browse button
6. Click on Start Job to run the shiny tutorial in the background
7. Copy the returned URL mentioned after Listening on string corresponding to this pattern http://127.0.0.1:<port_number>
8. Paste the URL in a new window browser to start the tutorial
9. Follow the steps and complete the exercises

• if you had already begun the tutorial, you can continue from where you left off (learnr keeps track of your progress)
• you may want to start over the tutorial if so click on Start Over button in the sidebar (caution: it will reset all your progress in the tutorial)

10. Continue working within the current shiny project

Run the tutorial on binder

Click on the following badge to run the tutorial on binder, it will open a new tab in your browser and you can start the tutorial from there:

Be patient, it could take a while to deploy the tutorial code on mybinder.org.
