R help - Nov 2023 - Can someone please have a look at this query on stackoverflow?

Dear all,

I have posted a query which has received a response but that is not
working on my computer.

Here is the query:

https://stackoverflow.com/questions/77387434/pdf-from-rmarkdown-landscape-and-aspectratio-169

Can someone please help me ?

Best Regards,
Ashim

I ran the code from the answer and it seems to work well. It, definitely,
is giving a landscape output.

---
title: "Testing landscape and aspect ratio"
output:
  pdf_document:
    number_sections: true
classoption:
  - landscape
  - "aspectratio=169"
header-includes:
   - \usepackage{dcolumn}
documentclass: article
geometry: margin=1.5cm---

```{r, out.extra='keepaspectratio=true', out.height='100%',
out.width="100%"}
plot(rnorm(100))
```

Dear Ashim,

I don't think the aspectratio is appropriate in this context because
it would imply that the beamer (LaTeX) class is used but you're actually
using the article (LaTeX) class.

You may use specifications of the geometry package rather than
specifying options to the class:

e.g. replace your current header:

---
title: "Testing landscape and aspect ratio"
output: 
  pdf_document:
    number_sections: true
classoption:
  - landscape
  - "aspectratio=169"
header-includes:
   - \usepackage{dcolumn} 
documentclass: article
geometry: margin=1.5cm
---

with this one:

---
title: "Testing landscape and aspect ratio"
output: 
  pdf_document:
    number_sections: true
header-includes:
   - \usepackage{dcolumn} 
documentclass: article
geometry: margin=1.5cm, paperwidth=24cm, paperheight=13.5cm 
---

Of course, you may change the exact dimensions and it will impact the
relative font sizes. I've tested it and it generates what you want.

Yours.
Olivier.
