Language in html_document - toc levels in learnr::tutorial - themes

[BB-Diesunddas]

Hi,

I am experienced in R, but new to learnr. I really like the concept. Now I am experimenting to prepare teaching material (for several university courses with 100+ participants).

Here are some questions, to which I didn't find a solution:

• if I use the output "html_document" instead of "learnr::tutorial", how do I change the language of the interactive code boxes? For the latter it works perfectly via yaml "language: xyz", but how to do it for "html_document"?
• one reason for using "html_document" is that its (floating) toc allows multiple levels of headings, so one can structure & navigate a large document much better. Is there a way to allow mutliple levels in "learnr::tutorial", it seems currently only to work with ##?
• There are several themes offered, is there a site or "themebrowser" to compare these side by side? (instead of everyone just diy)

Thank you for your work and help!

In this case you should be able to use the tutorial.language option, e.g. options(tutorial.language = "fr"). Alternatively, knitr::opts_knit$set(tutorial.language = "fr") should also work.

No there isn't, unfortunately.

This is a great idea but it doesn't currently exist. For now I'd recommend using a small, simple tutorial to step through themes until you find one you like.

Thank you for your reply. Still the language switch seems not to work for me in html_document. Here is a minimal example (trying all possible positions for the option without success):

---
title: "Language for html_document"
output:
#  learnr::tutorial:
#    language: fr
  html_document   
runtime: shiny_prerendered 
---


```{r setup, include=FALSE}
options(tutorial.language = "fr")
knitr::opts_knit$set(tutorial.language = "fr")
library(learnr)
options(tutorial.language = "fr")
knitr::opts_knit$set(tutorial.language = "fr")
```


```{r test, exercise = TRUE}

```

The generated document shows still "Start Over" and "Run Code" at the coding-box.
