title: Citing articles using roxygen2
body: <p>As in <a href="https://stackoverflow.com/q/10207564/1414455">this question</a>, I would like to include citations to articles in function documentation. I use <code>roxygen2</code> for all documentation, and it appears that there was a <a href="https://github.com/klutometis/roxygen/pull/90" rel="noreferrer">pull request</a> to <code>roxygen2</code> with the necessary functionality, but Hadley turned it down since <code>roxygen2</code> was in maintenance mode. Have things changed since then? Is there another way to cite/ include article references stored in BibTeX format?</p>
