Biblatex works because the style changes when I add
citation_package: biblatex. The problem is that biblatexoptions have no effect.
Only the biblio-style option works.
I also tried xelatex, pdflatex and lualatex.
output: bookdown::pdf_book: latex_engine: xelatex citation_package: biblatex biblatexoptions: [backend=biber, style=authoryear,citestyle=authoryear]
Can I pass these options as commandline parameters?
Is the following warning dangerous? Bookdown can not run latex multiple times.
Warning message: LaTeX Warning: There were undefined references. Package biblatex Warning: Please rerun LaTeX.
