I am using the papaja package to produce an APA style manuscript. I'm able to create word documents with the Rmd script but I get that error when the output is pdf_document. However, I am able to create a manuscript using the papaja template "APA article (6th edition) but this route requires a lot of script editing to remove the unnecessary code.

I suppose the issue has to do with threepartabble but I can't seem to find any guidance on this using R. I am using a Mac and have MacTex installed.

Answer 1

The fix was installing "kableExtra" For some reason the pdf does not render without it.
