namedropR provides ‘visual citations’ containing the metadata of a
scientific paper and a ‘QR’ code.
To install, simply run:
install.packages("namedropR")You can install the development version of namedropR from GitHub with:
# install.packages("devtools")
devtools::install_github("nucleic-acid/namedropR")A ‘visual citation’ is a banner containing an article’s title, authors, journal and year of a publication (s. example below).
One might want to include this in a presentation
- to back up one’s claims,
- to drop an important name,
- to boast about a publication in a ‘high impact journal’.
Some might even use this to genuinely point the audience to good resources for further reading.
On conferences, such banners are frequently displayed way too short for the audience to actually comprehend them (and often in a bad resolution). Creating visual citations requires manually taking a screenshot and placing it on the slide.
namedropR helps to generate visual citations conveniently (see below),
in high resolution and with a QR code. This allows the audience to
follow the reference while you are talking about it, instead of
looking it up in a reference list at the end of your talk.
There is also a less intrusive, compact style, as seen on the left.
This package accepts bibliographic information as ‘BibTeX’ and ‘BibLaTeX’ references and includes a QR code pointing to the ‘DOI’. If the ‘DOI’ is not available in the bibliography entry, but a ‘URL’ field instead, this is used. If neither is given, the QR code points to a search call at https://scholar.google.com with the available data as search terms.
bib_path <- "path/to/bibliography_file.bib"
# load the package
library('namedropR')
# create a visual citation as PNG with 'modern' design
drop_name(bib_path, cite_key = "SomeAuthor2010", export_as = "png", style = "modern")
# create a visual citation as HTML with 'compact' design
drop_name(bib_path, cite_key = "SomeAuthor2010", export_as = "html", style = "compact")
# drop_name() by default returns the file path,
# where the visual citation was stored as character string.
# Within an Rmarkdown/HTML presentation you can create and
# include the banner conveniently like so:
# PNG
knitr::include_graphics(drop_name(bib_path, cite_key = "SomeAuthor2010", export_as = "png", style = "clean"))
# HTML
htmltools::includeHTML(drop_name(bib_path, cite_key = "SomeAuthor2010", export_as = "html", style = "clean", use_xaringan = TRUE))
# To bulk-create VCs to include in another kind of document / presentation slides you can pass a vector of citation keys or pass no keys at all to render some or all bibliography entries respectively:
drop_name(bib_path, cite_key = c("SomeAuthor2010", "SomeOther2011", "YetAnother2012"), export_as = "png", style = "clean")
drop_name(bib_path, export_as = "png", style = "clean")Styling is possible via predefined designs or via custom ‘CSS’ to match the design of the HTML presentation like e.g. ‘xaringan’ or ‘revealJS’ (see the vignette for more options).
If you have ideas for Visual Citation styles and think, everyone should be able to use them, feel free to open an issue and describe the style or provide the CSS code, if you have one already.
If you want to speed things up, you can fork the project to create a pull request. Please also open an issue, so we can have a discussion, if needed. See the readme for details.

- This package is not intended as replacement for proper reference manager packages, but a tool to enrich scientific presentation slides. Hence the functionality is quite limited to this specific use case.
- previous versions (before v2.0) allowed passing
RefManageR::BibEntry()objects. This option was removed to eliminate dependency on the orphaned{bibtex}package. This might break code for users of initial releases of the package, but was needed to allow for CRAN submission.
