Welcome to the exciting world of interactivity in R! The learnr package provides a seamless way to transform any RMarkdown document into an engaging interactive tutorial. This guide will walk you through the process of creating these tutorials while highlighting their features.

What is the learnr Package?

The learnr package simplifies the development of interactive tutorials. A tutorial can include:

• Narrative content, figures, illustrations, and equations.
• Code exercises allowing users to edit and execute R code directly.
• Quiz questions for testing knowledge.
• Embedded videos from platforms like YouTube and Vimeo.
• Interactive components utilizing Shiny.

Moreover, learnr automatically saves progress, so users can return to where they left off without hassle.

Installation of learnr

To install the latest official release of the learnr package from CRAN, simply run the following command in your R console:

install.packages("learnr")

If you wish to try the latest development version from GitHub, use the remotes package:

# install.packages("remotes")
remotes::install_github("rstudio/learnr")

It’s worth noting that learnr works best with a recent version of RStudio (v1.0.136 or later). This ensures you have the necessary tools for running and previewing your tutorials efficiently.

Understanding the Code Structure

The installation methods above might look straightforward, but let’s delve deeper using an analogy. Imagine you want to bake a cake (your tutorial). First, you need ingredients (the right packages). The command install.packages("learnr") is like going to the store and buying the cake mix. If you want a custom flavor, the command remotes::install_github("rstudio/learnr") is equivalent to creating a special recipe that hasn’t been published yet—it’s a unique variation ready to be tested in your kitchen (your local R environment). Just ensure you have the right baking tools (update RStudio) to make your baking process smooth!

Troubleshooting

Are you facing issues while using the learnr package? Here are some common troubleshooting tips:

• Installation Errors: Ensure that R and RStudio are updated to the latest versions before installing the package.
• Interactive Components Not Displaying: Check whether you are using the correct version of RStudio that supports learnr (v1.0.136 or later).
• Code Execution Issues: Verify that all your code chunks are correctly formatted and have the necessary libraries loaded.
