raw_block: Mark character strings as raw blocks in R Markdown
In forks-micael/knitr: A General-Purpose Package for Dynamic Report Generation in R

Wraps content in a raw attribute block, which protects it from being escaped by Pandoc. See https://pandoc.org/MANUAL.html#generic-raw-attribute. Functions raw_latex() and raw_html() are shorthands of raw_block(x, 'latex') and raw_block(x, 'html'), respectively.

raw_block(x, type = "latex", ...)

raw_latex(x, ...)

raw_html(x, ...)

`x`	The character vector to be protected.
`type`	The type of raw blocks (i.e., the Pandoc output format). If you are not sure about the Pandoc output format of your document, insert a code chunk `knitr:::pandoc_to()` and see what it returns after the document is compiled.
`...`	Arguments to be passed to `asis_output()`.
