All slide decks
Fifteen revealjs presentations, in teaching order
Every deck opens as a full-screen presentation. Useful keys inside a deck: ? shows all shortcuts, o opens the slide overview, f goes full screen, and e switches to print view so you can save the deck as a PDF from your browser.
The Source link opens the .qmd behind each deck β the R code that produced every figure and table is in there.
