Cite R packages used in a project

Description

Find R packages used in a project, create a BibTeX file of references, and generate a document with formatted package citations. Alternatively, cite_packages can be run directly within an 'R Markdown' or 'Quarto' document to automatically include a paragraph citing all used packages and generate a bibliography.

Usage

cite_packages(
  output = c("file", "paragraph", "table", "citekeys"),
  out.dir = NULL,
  out.format = c("html", "docx", "pdf", "Rmd", "md", "tex-fragment", "tex-document"),
  citation.style = NULL,
  pkgs = "All",
  omit = c("grateful"),
  cite.tidyverse = TRUE,
  dependencies = FALSE,
  include.RStudio = FALSE,
  passive.voice = FALSE,
  out.file = "grateful-report",
  bib.file = "grateful-refs",
  ...
)
cite_packages(
  output = c("file", "paragraph", "table", "citekeys"),
  out.dir = NULL,
  out.format = c("html", "docx", "pdf", "Rmd", "md", "tex-fragment", "tex-document"),
  citation.style = NULL,
  pkgs = "All",
  omit = c("grateful"),
  cite.tidyverse = TRUE,
  dependencies = FALSE,
  include.RStudio = FALSE,
  passive.voice = FALSE,
  out.file = "grateful-report",
  bib.file = "grateful-refs",
  ...
)

Arguments

`output`	Either "file" to generate a separate document with formatted citations for all packages; "paragraph" to return a paragraph with in-text citations of used packages, suitable to be used within an 'R Markdown' or 'Quarto' document; "table" to return a table with package name, version, and citations, to be used in 'R Markdown' or 'Quarto'; "citekeys" to return a vector with citation keys. In all cases, a BibTeX file with package references is saved on disk (see `bib.file`).
`out.dir`	Directory to save the output document and a BibTeX file with the references. It is recommended to set `out.dir = getwd()`.
`out.format`	Output format when `output = "file"`: either "html" (the default), "docx" (Word), "pdf", "tex-fragment" (LaTeX fragment to be inserted into another LaTeX document), "tex-document" (full LaTeX document), "Rmd", or "md" (markdown). (Note that choosing "pdf" requires a working installation of LaTeX, see https://yihui.org/tinytex/).
`citation.style`	Optional. Citation style to format references for a particular journal (see https://bookdown.org/yihui/rmarkdown-cookbook/bibliography.html). If the CSL is not available in `out.dir`, it will be downloaded automatically from the official GitHub repository using `get_csl()`. If using `cite_packages()` within an R Markdown or Quarto document, `citation.style` should be `NULL` (the default). The citation style should instead be defined in the YAML metadata of the document (see https://pakillo.github.io/grateful/#using-grateful-with-rmarkdown-or-quarto).
`pkgs`	Character. Either "All" to include all packages used in scripts within the project/folder (the default), or "Session" to include only packages used in the current session. Alternatively, `pkgs` can also be a character vector of package names to get citations for. To cite R as well as the given packages, include "base" in `pkgs` (see examples).
`omit`	Character vector of package names to be omitted from the citation report. `grateful` is omitted by default. Use `omit = NULL` to include all packages.
`cite.tidyverse`	Logical. If `TRUE`, all tidyverse packages (dplyr, ggplot2, etc) will be collapsed into a single citation of the 'tidyverse', as recommended by the tidyverse team.
`dependencies`	Logical. Include the dependencies of your used packages? If `TRUE`, will include all the packages that your used packages depend on.
`include.RStudio`	Logical. If `TRUE`, adds a citation for the current version of RStudio.
`passive.voice`	Logical. If `TRUE`, uses passive voice in any paragraph generated for citations.
`out.file`	Desired name of the citation report to be created if `output = "file"`. Default is "grateful-report" (without extension).
`bib.file`	Desired name for the BibTeX file containing packages references ("grateful-refs" by default).
`...`	Other parameters passed to `renv::dependencies()`.

Details

cite_packages is a wrapper function that collects package names and versions and saves their citation information in a BibTeX file (using get_pkgs_info()).

Then, the function is designed to handle different use cases:

If output = "file", cite_packages() will generate an 'R Markdown' file which includes a paragraph with in-text citations of all packages, as well as a references list. This document can be knitted to various formats via out.format. References can be formatted for a particular journal using citation.style. Thus, output = "file" is best for obtaining a document separate from R, to just cut and paste citations.

If output = "paragraph", cite_packages() will return a paragraph with in-text citations of all packages, suitable to be used directly in an 'R Markdown' or 'Quarto' document. To do so, include a reference to the generated bib.file bibliography file in the YAML header of the document (see https://pakillo.github.io/grateful/index.html#using-grateful-within-rmarkdown).

Alternatively, if output = "table", cite_packages() will return a table with package names, versions, and citations. Thus, if using 'R Markdown' or 'Quarto', you can choose between getting a table or a text paragraph citing all packages.

Finally, you can use output = "citekeys" to obtain a vector of citation keys, and then call nocite_references() within an 'R Markdown' or 'Quarto' document to cite these packages in the reference list without mentioning them in the text.

Value

If output = "file", cite_packages will save two files in out.dir: a BibTeX file containing package references and a citation report with formatted citations. cite_packages will return the path to the citation report invisibly. If output = "table" or output = "paragraph", cite_packages will return a table or paragraph with package citations suitable to be used within 'R Markdown' or 'Quarto' documents.

Limitations

Citation keys are not guaranteed to be preserved when regenerated, particularly when packages are updated. This instability is not an issue when citations are used programmatically, as in the example below. But if references are put into the text manually, they may need to be updated periodically.

Examples



# To build a standalone document for citations
cite_packages(out.dir = tempdir())

# Format references for a particular journal:
cite_packages(citation.style = "peerj", out.dir = tempdir())

# Choose different output format:
cite_packages(out.format = "docx", out.dir = tempdir())

# Cite only packages currently loaded:
cite_packages(pkgs = "Session", out.dir = tempdir())

# Cite only user-provided packages:
cite_packages(pkgs = c("renv", "remotes", "knitr"), out.dir = tempdir())

# Cite R as well as user-provided packages
cite_packages(pkgs = c("base", "renv", "remotes", "knitr"), out.dir = tempdir())


# To include citations in an R Markdown or Quarto file

# include this in YAML header:
# bibliography: grateful-refs.bib

# then call cite_packages within an R chunk:
cite_packages(output = "paragraph", out.dir = tempdir())

# To include package citations in the reference list of an Rmarkdown document
# without citing them in the text, include this in a chunk:
nocite_references(cite_packages(output = "citekeys", out.dir = tempdir()))

# To build a standalone document for citations
cite_packages(out.dir = tempdir())

# Format references for a particular journal:
cite_packages(citation.style = "peerj", out.dir = tempdir())

# Choose different output format:
cite_packages(out.format = "docx", out.dir = tempdir())

# Cite only packages currently loaded:
cite_packages(pkgs = "Session", out.dir = tempdir())

# Cite only user-provided packages:
cite_packages(pkgs = c("renv", "remotes", "knitr"), out.dir = tempdir())

# Cite R as well as user-provided packages
cite_packages(pkgs = c("base", "renv", "remotes", "knitr"), out.dir = tempdir())


# To include citations in an R Markdown or Quarto file

# include this in YAML header:
# bibliography: grateful-refs.bib

# then call cite_packages within an R chunk:
cite_packages(output = "paragraph", out.dir = tempdir())

# To include package citations in the reference list of an Rmarkdown document
# without citing them in the text, include this in a chunk:
nocite_references(cite_packages(output = "citekeys", out.dir = tempdir()))

Usage

get_pkgs_info(
  pkgs = "All",
  out.dir = NULL,
  omit = c("grateful"),
  cite.tidyverse = TRUE,

  omit = c("grateful"),
  cite.tidyverse = TRUE,
  dependencies = FALSE,
  bib.file = "grateful-refs",
  include.RStudio = FALSE,
  ...
)

Arguments

`pkgs`	Character. Either "All" to include all packages used in scripts within the project/folder (the default), or "Session" to include only packages used in the current session. Alternatively, `pkgs` can also be a character vector of package names to get citations for. To cite R as well as the given packages, include "base" in `pkgs` (see examples).
`out.dir`	Directory to save the BibTeX file with references. It is recommended to set `out.dir = getwd()`.
`omit`	Character vector of package names to be omitted from the citation report. `grateful` is omitted by default. Use `omit = NULL` to include all packages.
`cite.tidyverse`	Logical. If `TRUE`, all tidyverse packages (dplyr, ggplot2, etc) will be collapsed into a single citation of the 'tidyverse', as recommended by the tidyverse team.

Generate Nocite Block

Description

Include a metadata block of citation keys for including citations in references file without in-text citations.

Usage

nocite_references(citekeys, citation_processor = c("pandoc", "latex"))
nocite_references(citekeys, citation_processor = c("pandoc", "latex"))

Arguments

citekeys

Vector of citation keys in reference to a relevant BibTeX file.

citation_processor

Mechanism for citation processing when knitting to PDF or otherwise using LaTeX. Selects the appropriate formatting of the nocite command. Either "pandoc" or "latex". If processing with pandoc-citeproc, use the nocite metadata block. If processing via a LaTeX processor such as natbib or biblatex, put in the LaTeX \nocite{} command directly. If knitting to any non-LaTeX format, this parameter is ignored, and a pandoc-citeproc style block is used.

Details

When passed a list of citation keys, adds the @ to each, then builds the nocite metadata field, returning via "as-is" output. Run this function either inline or within a code chunk (with echo = FALSE) to include this metadata block within an RMarkdown document. The code chunk need not explicitly state results = 'asis'.

Call nocite_references with either style = 'pandoc' or style = 'latex' depending on whether you are processing citations with pandoc-citeproc or a LaTeX citation processor such as biblatex or natbib.

This function is intended to cite R packages with citation keys passed from get_citations() or cite_packages(output = "citekeys"), but can accept an arbitrary vector of citation keys (without @) found in a BibTeX file referenced in the YAML header.

Value

"As is" text of metadata block, with comma-separated list of citation keys.
