rticles::joss_article does not work with r chunks and image chunks.

[benyamindsmith]

I am working with rticles to write a JOSS article and it would be nice to preview how the article would look when I am running it.

I have noticed that when specifying output: rticles::joss_article realized that I am unable to knit my .Rmd file to a pdf.

Minimal Example (example.Rmd)

---
title: "Example"
author: "Benjamin Smith"
date: "`r Sys.Date()`"
output:
  rticles::joss_article
---

# Introduction 

`This is some text`

# Some R code

\```{r}
print("This is some R output!")
\```

# An Image

![This is an image!!](https://pkgs.rstudio.com/rticles/logo.png)

I did my fair share of looking at issues but none of them seem to point to the root of the problem.

Similar issues:

• JOSS template error with bookdown #564 Looks unaddressed
• Unable to knit the joss_article template #389
• rticles::joss_article removes hyperlinks from figure captions if out.width is used for chunk options #379

I do already have tinytex installed so that could not be the issue.

This is related to

• Pandoc 3.2.1 update on LaTeX writer  #571

Templates needs update for a newer Pandoc version, while not breaking older version of Pandoc 😞

I'll come back to this very soon.

@cderv thanks for letting me know. I'm sure other rticles users will encounter the same problem.

The fix that I'm doing now is just using an older version of pandoc (I used 3.1.13 without any issues when using rticles)
