Chapitre4 Footnotes and citations

4.1 Footnotes

Footnotes are put inside the square brackets after a caret ^[]. Like this one ¹¹.

4.2 Citations

Reference items in your bibliography file(s) using @key.

For example, we are using the bookdown package¹² (check out the last code chunk in index.Rmd to see how this citation key was added) in this sample book, which was built on top of R Markdown and knitr¹³ (this citation was added manually in an external file book.bib). Note that the .bib files need to be listed in the index.Rmd with the YAML bibliography key.

The bs4_book theme makes footnotes appear inline when you click on them. In this example book, we added csl: chicago-fullnote-bibliography.csl to the index.Rmd YAML, and include the .csl file. To download a new style, we recommend: https://www.zotero.org/styles/

The RStudio Visual Markdown Editor can also make it easier to insert citations: https://rstudio.github.io/visual-markdown-editing/#/citations
