RTutor is an R package that allows to develop interactive R exercises. Problem sets can be solved off-line or can be hosted in the web with shinyapps.io. Problem sets can be designed as a Markdown .rmd file (to be solved directly in RStudio) or use a browser-based interface powered by RStudio’s Shiny. While the web interface looks nicer, I personally use problem sets in the Markdown format when teaching advanced economic classes.
You can try out the Rmarkdown version of RTutor via RStudio Cloud:
For the web-based interface, several students at Ulm University have created very nice problem sets that allow to interactively replicate the main insights of interesting economic articles and to learn a bit about R and econometrics. Before developing your own problem sets, you may want to try out some of these examples:
RTutor and some required packages are not hosted on CRAN (while CRAN is great it takes a lot of time to maintain several packages there). I have created an own Github based R repository, from which you can install RTutor by using the following code:
Note: If you want to create your own web-based RTutor problem sets and upload them on shinyapps.io, you need to install RTutor and required packages directly from Github and CRAN as explained below. That is because shinyapps.io only works with R packages directly installed from Github or CRAN.
To install RTutor and required packages directly from Github and CRAN, you can use the small function in the following gist:
Copy the code in the link into your R console and then run:
Depending on your devtools version, also the following code may work directly (yet source_gist is buggy in some devtools versions):
If you only want to update the RTutor package (and have the other packages already installed). You can just type:
(You may have to restart your R session / RStudio for the update to work.)
Take a look at the manuals for documentation of how to create own problem sets.
If you have suggestions or find bugs, please don’t hesitate to open an issue on the Github page.
