Dimension of plot produced by rainette_plot() in HTML rendering

[gabrielparriaux]

Hello @juba,

I’m using Quarto to render reports from my analyzes in R.

I produce a plot of my clustering with rainette_plot() and the problem with the results from clustering is that over a few number of clusters, the plot doesn't render very well in HTML I would like to make it full width to see if it’s better.

I found some instructions to render content full width on this page: https://quarto.org/docs/authoring/article-layout.html, using this option for the code chunk:

#| column: page

But when I use it with the code chunk that produces my rainette_plot(), the plot doesn't increase to full width.

Is there a parameter that we can use in the function to make it render the result full width?

I tried something similar when rendering to PDF, I wanted to have a page in landscape format. I saw instructions here to have a landscape page in PDF: https://stackoverflow.com/questions/25849814/rstudio-rmarkdown-both-portrait-and-landscape-layout-in-a-single-pdf. It works, but same problem: the plot doesn't render in full width.

Thanks a lot for your help!

Hi,

Would you have a sample HTML document I could take a look at ?

Thanks !

Hi,

Thank you for your help.

Just to be sure that I was understood correctly: the HTML file is generated by the rendering in Quarto, I don't produce it myself manually.

Here is an extract from the code in the Quarto file, with the YAML header and the code chunk in R that draws the plot:

---
title: "PhD thesis GP --- class 03, lesson 03"
toc: true
toc-depth: 4
number-sections: true
format:
  html:
    code-fold: true
    df-print: kable
  pdf:
    colorlinks: true
    tbl-colwidths: auto
    df-print: paged
---

### Clustering of the discourse of the two teachers

```{r}
#| label: compute_clustering
#| output: false
#| echo: false

# here I create the dfm and proceed to Reinert's clustering

#| label: display_clustering
#| output: true
#| echo: false
#| column: page

## Clustering description plot
rainette_plot(
  res, dtm, k = clusters_number,
  n_terms = 30,
  free_scales = FALSE,
  measure = "chi2",
  show_negative = TRUE,
  text_size = 12
)

and the HTML that is generated for this part is this:

```html
<section id="clustering-of-the-discourse-of-the-two-teachers" class="level3 page-columns page-full" data-number="1.4">
<h3 data-number="1.4" class="anchored" data-anchor-id="clustering-of-the-discourse-of-the-two-teachers"><span class="header-section-number">1.4</span> Clustering of the discourse of the two teachers</h3>
<div class="cell page-columns page-full">
<div class="cell-output-display column-page">
<p><img src="class03_lesson03_files/figure-html/display_clustering-1.png" class="img-fluid" width="672"></p>
</div>
</div>
</section>

Does it help or would you need the whole .qmd and .html files?

[juba]

Did you try modifying the fig-width and fig-height options ?

https://quarto.org/docs/computations/execution-options.html#figure-options

[gabrielparriaux]

Yes, and it works, but it's not perfect…

I would like to define those options on a chunk level and not document-wide in the YAML header. When defined in the code chunks options, it doesn't seem possible to define a different format for HTML or PDF.

So, do I understand correctly that there is no parameter in the rainette_plot() function to define the format of the output, but that the format should be managed on the document level or chunk level?

[juba]

Yes, you're right. rainette creates the plot, but its dimensions, ppi, etc. are not handled by it.

[gabrielparriaux]

Ok thanks a lot @juba, I will try to manage those Quarto options somehow!
