bookdown section label not referenced after backticks

I would like to use a code part in the name of a chapter / section, and reference that using a label.

# Venn diagrams: function `venn()`{#venn}

If not using the backticks, the reference works as expected but using the backticks prevents the label to be referenced:

Warning messages:
1: The label(s) venn not found 
2: The label(s) venn not found

Is there a way to obtain this?

Solution

  • This is a known issue in Pandoc, and I think it is by design. You have to either remove the backticks, or insert something between venn() and the section ID, e.g.,

    # Venn diagrams: the `venn()` function {#venn}
