knitcitations: Citations for knitr markdown files
knitcitations provides the ability to create dynamic
citations in which the bibliographic information is pulled from
the web rather than having to be entered into a local database
such as bibtex ahead of time. Knitcitations is primarily aimed
at authoring in the R markdown format, and can provide outputs
for web-based authoring such as linked text and tooltips over
inline citations. Cite using a DOI, URL, or bibtex file key.
