How do I reference a figure sub-panel with no separation?

[jessicaguo]

Description

The @fig-1 notation is super handy and easy to remember and type. However, I often refer to subpanels by letter. How can I remove the space between the figure number and the letter?

I can do @fig-1 a, which results in a space, and if I remove the space obviously Quarto thinks I'm referring to a non-existent @fig-1a.

There's no current way to do this, see #5481 where we're tracking the issue.

"when the subfigure is not being created in Quarto" I don't understand what you mean.

We do support control for space-after-numbering for custom crossrefs: https://quarto.org/docs/authoring/cross-references-custom.html#example-supplemental-figures

You should be able to achieve what you need by switching all your crossrefs to custom crossrefs, and then render them as desired using the configuration described in the docs above.

For regular crossrefs, the way to do it depends on which format you're targeting. In LaTeX, you'll need to configure hyperref yourself (since that's what Quarto does). In HTML,

Thank you for your quick reply.

• By "when the subfigure is not being created in Quarto", I mean imagine that you used {patchwork} to create a figure with subfigures included and labeled in a single PNG as opposed to including and labeling separate figures in Quarto (https://quarto.org/docs/authoring/figures.html#subfigures).
• The example for custom crossrefs has a space-before-numbering option for something like Figure S1 (rather than Figure S 1). But when I replace space-before-numbering with space-after-numbering, I receive this error:

ℹ The error happened in location crossref:custom:0:space-after-numbering.
ℹ Did you mean space-before-numbering?

ERROR: Render failed due to invalid YAML.

• Currently, I'm rendering output in Word.

Sorry, I did mean space-before-numbering.

Can you try something like @fig-1[]{.empty}a? That is, you create an intentionally empty span instead of a space between the two parts of the thing you want to write. It's a fairly ugly hack but might just work well enough for you.

EDIT: As @pjotrhey suggests, the syntax [@fig-1]A is much cleaner.

[JeffreyRStevens]

That works! Many thanks, @cscheid!

[pjotrhey]

You can also just use [@fig-1]A, see https://quarto.org/docs/authoring/cross-references.html#references

Thanks. You're exactly right, and I should know it, I helped write that page!
