Parameters are for computations (code cells) not for metadata. See the documentation: https://quarto.org/docs/computations/parameters.html

See also the documentation about Pandoc's template system: https://pandoc.org/MANUAL.html#template-syntax

What you need is to change metadata, you can find multiple examples of this in the other discussions.

One example:

• https://github.com/mcanouil/generate-quarto-invoices

See other discussions about Typst: https://github.com/quarto-dev/quarto-cli/discussions?discussions_q=is%3Aopen+label%3Atypst

Thanks. So I understand that I have to use {}. but how to run it using purrr or something? is there a way?

[mcanouil]

If you intend to use the R wrapper, I strongly suggest to read the documentation of the function you are using.
With my reply and the documentation you have everything.

follow up to this. Now i am trying to change colours dynamically. When i manually change species in Yaml of penguins.qmd, it works. But when i use render.R it does not. What Am i doing wrong here?

You need to provide a clear description with a small reproducible example when asking something or your chances to get a useful answer is close to zero.

This being said, there are also other threads discussing this kind of things.

I am sorry. I thought since it is same thread GitHub repo was available. The issue is this: I have penguins.qmd which is parameterised. The qmd file works as expected and creates a dynamic report which has also some nice colour codes based on the input parameter. But when I use render.R to create reports for all species, everything works except the colour coding. I can’t find a way to do this
