Overview

About

Maintained by Achim ZeileisCRAN page ↗Codeberg ↗Website ↗Issues ↗

Automatic generation of quizzes or individual questions for 'learnr' tutorials based on 'R/exams' exercises.

Changes in 0.1-1

An exams2learnr tutorial is available on the R/exams web page: <https://www.R-exams.org/tutorials/exams2learnr/>.
Code repository changed from R-Forge to Codeberg at: <https://codeberg.org/zeileis/exams2learnr/>
Handle the case with run_quiz(..., dir = NULL, edir = NULL) better: edir is set to the current working directory so that local exercise files are found when using a temporary dir.
Adapt exams2learnr() to knitr 1.48 where it is necessary to unlock a code chunk before re-labeling it. This is used internally to propagate labels correctly.

Install

R (CRAN)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("exams2learnr", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-exams2learnr

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-exams2learnr

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-exams2learnr

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
