Dynamic figure size

[slamao]

Hi,
thank you very much for this great tool.

I would like to ask if it is possible to set a dynamic figure size?
You can do this easily in RMarkdown (see below what I mean) but I cannot find a way how to do that in Quarto (using knitr).

```{r}
my_width <- 10

```{r fig.width=my_width}
<plot code>

Any chances this works (or will work) in Quarto as well?

Many thanks!

Quarto does not support only YAML values for its chunk definition. However, for knitr compatibility, there is special support
See https://quarto.org/docs/computations/r.html#chunk-options

• First you could still pass option as you do in R Markdown. So about "Any chances this works (or will work) in Quarto as well?" Did you try it ? Because it should work

• You can use YAML new syntax, but use special !expr syntax as in the doc - Only drawback: It applies on knitr only within Quarto. Not other computation engine.

Hope it helps

Thanks Christophe, amazing, this works!! Thanks a lot!

To summarise for any future reference, use this in quarto to make your plot size dynamic:

```{r}
#| fig-width: !expr my_width
<plot code>
