Markdown tables fail: Undefined control sequence. <argument> \@@magyar@captionfix

[mdozmorov]

beamer_presentation: default with a Markdown table fails with error ! Undefined control sequence. <argument> \@@magyar@captionfix. Pure markdown tables, knit::kable and pander::pander tables produce the same error. Yet, knitting to pdf_document: default works. This issue relates to #1360 and a question on RStudio Community, and can be resolved by manually putting \relax into the .tex file, as described and compiling it into pdf. But this is clearly unsustainable.

Minimal example

---
output:
  beamer_presentation: default
---

## That works

```{r}
cars[1:5,]
```

<!--
## That does not

|    | a2 | a3 |
|----|----|----|
| s1 | 1  | 2  |
| s2 | 3  | 4  |
-->

## That also works

```{r}
knitr::kable(cars[1:5,], format = "latex")
```

## That does not

```{r}
knitr::kable(cars[1:5,])
# pander::pander(cars[1:5, ])
# Any command above throws an error:
# ! Undefined control sequence.
# <argument> \@@magyar@captionfix 
```

According to the TeX.SE post you mentioned, this was a bug in a certain LaTeX package that has been fixed half a year ago. I cannot reproduce this issue with the latest versions of LaTeX packages. You may consider using TinyTeX if you are currently using MacTeX or TeX Live:

tinytex::install_tinytex()

[mdozmorov]

After uninstalling MacTex and installing tinytex::install_tinytex(), all works. Thanks, @yihui!
