r - Rmarkdown with pdf output and plain LaTeX code block -


how plain code block rmarkdown when code block contains tex code , 1 wants pdf output ?

for example, not work:

--- title: "untitled" output:   pdf_document:     keep_tex: yes ---  hello !  ``` \begin{verbatim} verbatim text \end{verbatim} ```

this generated error: ! latex error: \begin{document} ended \end{verbatim}.

of course, can do:

```{r, eval=false} \begin{verbatim} verbatim text \end{verbatim} ```

but problem when doing that, code block in output can highlighted r highlighting colors (not example above, occur in cases).

you use pandoc's verbatim fenced code block syntax:

~~~latex \begin{verbatim} verbatim text \end{verbatim} ~~~

or also:

```latex \begin{verbatim} verbatim text \end{verbatim} ```
