Chapitre 2 : Le 2

Le premier titre du chap 2

Other times, I have not used X (yet!). This happened to me recently when I was asked:

“Why aren’t people using reveal.js for slides with R Markdown? What are the problems with reveal.js, and how can we fix them?".

What is reveal.js? Here is a demo deck:

Air quality

with(airquality, boxplot(Temp ~ Month))

with(airquality, plot(Ozone ~ Temp))

mlev <- levels(with(airquality, as.factor(Month)))
with(airquality, plot(Ozone ~ Temp, 
                      pch = as.numeric(mlev), 
                      col = mlev))
