In skranz/RTutor: Interactive R problem sets with automatic testing of solutions and automatic hints

Problemset Quizzes

Example of different quiz formats in a shiny based RTutor problemset

Adapt the working directory below and run the setup chunk in RStudio. This creates the problem set files and the sample solution from this solution file.

< ignore

library(RTutor)
setwd("D:/libraries/RTutor/RTutor/inst/examples")
ps.name = "QuizExample"; sol.file = paste0(ps.name,"_sol.Rmd")
# Important to add the parameter addons="quiz" !
create.ps(sol.file=sol.file, ps.name=ps.name,libs=libs, addons="quiz")
show.ps(ps.name)
stop()

Note that every problem set must have at least at one chunk in order to compile without error. Yeah... I was simply to lazy to implement all extra handling for problem sets without chunks, since the whole idea of RTutor is to have chunks.

Therefore one chunk at the end...

#< task_notest
(0.3-0.2-0.1)==0
#>

So better don't build rockets with R...
