In the .Rmd below I have includes: in_header: for pdf output and includes: before_body: for docx output. Is there something analogous for docx output?
My current hack is to include the <!--- For DOCX Only ---> code chunk conditionally when producing docx output. But I'd prefer not to have this clutter up the body of my .Rmd and move it out into some sort of preamble-word.tex file.
