RMarkdown knitting error papaja apa6 - rmdfiltr add wordcount filter

Question

I get the following error when knitting papaja::apa6_pdf docs. I'm running R version 3.6.2 with macOS Mojave (10.14.6) on my MacBook Pro. Any ideas?

Error in rmdfiltr::add_wordcount_filter(args, report = "warn") : 
  unused argument (report = "warn")
Calls: <Anonymous> -> <Anonymous> -> pdf_pre_processor
Execution halted

Answer 1

This error is caused by incompatible versions of papaja and rmdfiltr. Updating papaja (e.g. devtools::install_github("crsh/papaja@devel")) should fix this issue.
