R/exams docx output does not include images

I'm creating a written exam and am having trouble getting exams2pandoc() to include PNG question images in the word docx output. When I test with exams2html() instead, it successfully includes the images. Is there something I'm missing here?

My rmd files look like this:

Question
========
Susanne ist die einzige Herstellerin für Schokolade aus Schafsmilch. Die Kosten der Gesamtherstellung betragen C(q)=5q. Täglich kommen an ihrem Laden 10 Personen vorbei.

```{r, echo = FALSE, results = "hide"}

And when I do:

## Generate initial exam draw word docx
set.seed(sd)
exams2pandoc(draft, dir = paste0(path0, draftop_dir), n = 1, name = paste0("exam_", year, date, "_DRAFT_sd", sd, "_"), nsamp = 1, type = "docx", question = "" , solution = FALSE)

The docx output has no images, even though the html output does when I do:

set.seed(sd)
exams2html(draft, dir = paste0(path0, draftop_dir), n = 1, name = paste0("exam_", year, date, "_DRAFT_sd", sd, "_"), nsamp = 1, question = "" , solution = FALSE) # without solutions
Solution

  • Details:

    Thanks for pointing out this bug. It was caused by pandoc introducing a new LaTeX macro \pandocbounded{} that the default LaTeX template in exams2pandoc() did not support yet. (For the general problem see this description in GitHub projects #1 and #2.)

    Workaround:

    Instead of using the default LaTeX template you can also use the HTML template that is shipped with exams2pandoc() which avoids the problem:

    exams2pandoc(draft, template = "plain.html", ...)

    Fix:

    In version 2.4-3 of R/exams (released on CRAN in December 2025) the default LaTeX template is also fixed. With that version it is possible again to use

    exams2pandoc(draft, ...)
