@joeroe Not making any promises, but I got inspired by your suggestion and it seems like it could be a good side project, so I've set up a (so far barren) repository for the R package "gialoadr": https://codeberg.org/isakro/gialoadr

I assume it will remain an experimental thing, but most of the work in this field appears to happen in Fortran, Matlab and Python, so it would've been nice to make a small contribution to the R ecosystem. Any contribution is appreciated If you ever get curious again:)

@geospacedman Not everything you asked for, but an attempt based on https://quarto.org/docs/authoring/contents.html

This is the plot that we are going to make

{{< contents a-cell >}}

Here is the code for making the plot

::: {#a-cell}
```{r}
#| echo: false
#| label: plot-code
plot(sample(1:10), sample(1:10))
```
:::

```{r}
#| echo: true
#| eval: false
#| label: plot-code
```

The plot again

{{< contents a-cell >}}

And code yet again
```{r}
#| echo: true
#| eval: false
#| label: plot-code
```
