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

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.

Dear Olivier,

Many thanks for your reply.

This works well for me.

How did you come up with the pagewidth / pageheight numbers?  I do
understand that their ratio = 16:9,
but how did you choose these numbers?

Best Regards,
Ashim
