yml_reference: Write references as YAML fields

Description

yml_reference() creates YAML fields for references to be used in citation. reference() is a simple function to add references to yml_reference(). The easiest way to add references to an R Markdown file is to use a bibliography file, such as .bib, in the bibliography field (see yml_citations()). For documents with very few references, however, it might be useful to make the references self-contained in the YAML. yml_reference() can also transform to YAML bibentry and citation objects created bybibentry() and citation(). To cite many R packages and convert the references to YAML, it may be better to use knitr::write_bib() to write a bibliography file and convert it with bib2yml().

Usage

yml_reference(.yml, ..., .bibentry = NULL)
reference(id = NULL, ...)

Value

a yml object

Arguments

.yml

a yml object created by yml(), as_yml(), or returned by a yml_*() function

...

Fields relevant to the citation (e.g. bibtex fields)

.bibentry

An object created by bibentry() or citation(). Note that this requires pandoc-citeproc to be installed.

id

a character vector to use as the reference ID
