Reuse chunks

[FCACollin]

As a statistical programmer, using R and R Markdown, I was used to reuse code chunks such as explained here: https://bookdown.org/yihui/rmarkdown-cookbook/reuse-chunks.html.

Here is a code chunk that is not evaluated:

```{r, chunk-one, eval=FALSE}
1 + 1
2 + 2
```

Now we actually evaluate it:

```{r, chunk-one, eval=TRUE}
```

And I can evaluate it later again in the same document:

```{r, chunk-one, eval=TRUE}
```

I have attempted to find information about this feature for quarto documents, with no success. Do you know if this is implemented somehow in quarto?

Thanks in advance.

Everything that works with knitr should work with Quarto.

So this works

At least on my side with latest version.

Is this correctly working for you ?

Thanks for trying. At least now I know that it should work although it does not work yet on machine...

I am working on docker image rocker/verse:4.2.0. When I render the example:

I have added the sessioninfo::session_info() below. Any idea about what could be the root cause of the problem?

I think this is because there was an issue in Quarto that is now fixed #1034
So you should update your quarto version to at least v0.9.499 but latest would be best

Thanks for the hint and the news. I confirm:
