Error when loading kableExtra in markdown file after updating to R 4.3.0

Question

After updating to R 4.3.0 (on macOS 13.3.1) I get an error message, when compiling a markdown document:

Error: package or namespace load failed for 'kableExtra':
 .onLoad failed in loadNamespace() for 'kableExtra', details:
  call:!is.null(rmarkdown::metadata$output)&&rmarkdown::metadata$output%in%
  error: 'length = 3' in coercion to 'logical(1)'
Execution halted

Running the individual chunks in R Studio works without error message.

I already re-installed kableExtra with all dependencies.

According to the R news Calling && or || with LHS or (if evaluated) RHS of length greater than one is now always an error, with a report of the form 'length = 4' in coercion to 'logical(1)' – Rascally

It is a known issue, you need to install patched version from github: github.com/haozhu233/kableExtra/issues/750 – Ebeneser

Your "output" section of the YAML for your document includes 3 entries. Reduce it to one entry and you'll work around the bug in kableExtra. – Tseng

If installing dev patch does not work, then remove pdf from YAML output: html_document: default pdf_document: default – Stearoptene
