Lightweight R Markdown Syntax Highlighting in Shiny

shiny-highlight-rmarkdown

Offers renderRmd() and rmdOutput(): syntax highlighting for R Markdown output in Shiny using highlight.js.

Also offers renderRcode() and rcodeOutput() for R code output syntax highlighting.

You can use either one independently or use the two together.

or

Why

• shiny:::showcaseUI and codeModules::renderCode offer an R syntax highlighting solution but do not support R Markdown.
• Sometimes you want a lightweight R or R Markdown syntax highlighting solution in Shiny that does not involve introducing dependencies such as shinyAce.

First, they take the dinglebop, and they smooth it out with a bunch of schleem.
