Would you have a draft of something you tried?

You can include a small fake Quarto document following https://quarto.org/bug-reports.html.

```{r}
#| label: fig1
#| fig-cap: "Cars"
#| warning: false
#| echo: false

plot(cars)
!```

tried every setting, but nothing help

#| column: body-right
#| column: screen-right

#| column: screen-inset-shaded
#| layout-nrow: 1

Found solution from tex.stackexchange

Don't know how to make same with quarto

[mcanouil]

Ok, so what you want is a figure that spread across columns.

Then, this is a LaTeX question, where the answer is to use the figure* environment and not figure (default).
knitr has the fig.env chunk option (see https://yihui.org/knitr/options/#chunk-options), which you can set #| fig.env: figure*.

[megane999]

Thank you very much!
It is working, but I i don't know what to do when I have option #| layout-ncol: 2

I mean rendered tex file don't change environment for two figures layout

Again:

#| label: fig1
#| fig-cap: "Cars"
#| warning: false
#| echo: false
#| fig.env: figure*


plot(cars)

this code working good

#| layout-ncol: 2
#| label: fig-cars2
#| fig-cap:
#|   - "Cars1"
#|   - "Cars2"
#| warning: false
#| echo: false
#| fig.env: figure*

plot(cars)

plot(pressure)

these one not working

tex output

\begin{figure}

\begin{minipage}[t]{0.50\linewidth}

{\centering 

\raisebox{-\height}{

\includegraphics{quarto_files/figure-pdf/fig-cars2-1.pdf}

What's the output you expect for the two plots?
To be as a single figure spreading across columns?
To have each of the subfigures to spread across columns?

[megane999]

To be a big panel with >2 Figures, and this panel should to be across all columns.

example:

[mcanouil]

I suggest you use patchwork (https://patchwork.data-imaginist.com/articles/guides/assembly.html) which can handle both base and ggplot2 plots.

Quarto layout is independent of computation, i.e., it can't combine plots like this.
Or in a different way, using subcaption, see https://quarto.org/docs/authoring/figures.html#subcaptions, but then, Quarto might use it's own LaTeX environment to set the minipage layout, this I would build one single figure/image using patchwork which would allow the annotation "A", "B", etc.

[megane999]

Thank you a lot, for your answer. I appreciate your feedback.

Hi @mcanouil ,

I have the same question but in my case the image for the figure is not coming from the evaluation of a code chunk, i.e. I can't use #| fig.env: figure*. So is there a way of ![Elephant](elephant.png) generating a \figure*{}?

I think this might be quite common as many journal templates use two column layouts...

[mcanouil]

Why can't you?
The option is not specific to computation figures, see https://quarto.org/docs/authoring/figures.html#latex-figures.

[ramiromagno]

Because I am ignorant! :) I completely missed that from the documentation. Thanks a lot!
