Check-Fields and Check-Boxes for 'rmarkdown'

v0.0.13 · Sep 26, 2025 · GPL (>= 2)
CRAN GitHub Mirror

Description

Creates auto-grading check-fields and check-boxes for 'rmarkdown' or 'quarto' HTML. It can be used in class, when teacher share materials and tasks, so students can solve some problems and check their work. In contrast to the 'learnr' package, the 'checkdown' package works serverlessly without 'shiny'.
