demoR

Overview

demoR is a set of tools for formatting R code for presentations, teaching demonstrations, and much more:

The demo_*() functions prepare your source code to be both evaluated and displayed by knitr::knit().
The hlt_*() functions add text display formatting to printed code.

These combine naturally within code chunks in R Markdown files via code chunk options. You can learn more about them in vignette("demoR").
