Latex shell-escape options in YAML header don't use

Question

I\'m writing a report on Rmarkdovn but when you try to compile - pandoc_args options ignored when compile pdf.

I find this question: Is it possible to include svg image

Answer 1

R Markdown documents are compiled to PDF via tinytex::latexmk(). To enable the -shell-escape option for your LaTeX engine, you may set the global option tinytex.engine_args, e.g., add this code chunk to your document:

```{r, include=FALSE}
options(tinytex.engine_args = '-shell-escape')
```

See the help page ?tinytex::latexmk for more information.

The LaTeX engine is called by tinytex::latexmk() instead of Pandoc, so the Pandoc argument --pdf-engine-opt won't work.
