How do I get a long (more than 1 page) bibliograph

Question

I have an issue rendering bibliographies covering more than one page as only the first one is printed using RMarkdown and beamer output.

The same question has been posted at http://rmarkdown.rstudio.com/authoring_bibliographies_and_citations.html#comment-2398115545 but without any help.

title: "Sample Document"
output: beamer_presentation
bibliography: bibliography.bib

Answer 1

You can force a slide to be continued on the next one by setting its class to allowframebreaks. Just do this for your last slide. From the pandoc mailing-list:

## References {.allowframebreaks} 

Edit: knitr has a setting that prevents this solution from working out of the box with rmarkdown. See this question for a solution.
