Hi all,
When producing a PDF from an RMarkdown document, it is possible to change the underlying .tex based tokens such as KeywordTok, AttributeTok, FunctionTok etc.
I would like to do the same for a package vignette. I searched everywhere (over the internet, inside package rmarkdown .css files etc.) but I am still unable to get this done. For instance, changing the colors from the bottom of rmarkdown/templates/html_vignette/resources/vignette.css (e.g. span.kw, span.co ) doesn't seem to have any effect when re-knitting the .Rmd document.
I also tried to change that file and supply it as a custom .css inside the yaml header, and still no good result.
I would be grateful for any hint,

To answer my own question, the problem was an older Pandoc version. Updating Pandoc suddently solved everything, as described here:

The Vignette syntax highlighting does not seem to follow the general structure o… f the html classes.
Something like `aa <- c(1, 2)` is rendered in the html version as
```html
aa <-<span class="st"> </span><span class="kw">c</span>(<span class="dv">1</span>, <span class="dv">2</span>)
```
I believe the function `c()` should in fact have a class "fu" (not keyword "kw"). Similarly, something like `runif(n = 3)` is rendered as:
```html
<span class="kw">runif</span>(<span class="dt">n =</span> <span class="dv">3</span>)
```
where the argument `n` should have a different class from DataType ("dt"), perhaps "at" if I am not mistaken. Is there a special reason why these classes are mixed up?
Below is the output from:
