Cite R and R Packages

Add citations to R and R packages in an R Markdown report.

Usage

cite_r(pkgs = c("tidyverse", "gtsummary"), add_citations = TRUE)

Arguments

pkgs

character vector of package names to cite. Default is c("tidyverse", "gtsummary"). NULL is acceptable.

add_citations

logical indicating whether to include the bibtex citations of R and the packages. Default is TRUE. When TRUE, we expect the R markdown file to reference a bib file including the references for each package listed in the pkgs= argument. The cite key for each of these entries must match the package name. Also, the file must include an entry for R with cite key 'r'.

R Markdown

Below is an example how the cite_r() function would be used in an R Markdown report.

---
output: html_document
bibliography: references.bib

Analyses were conducted with `r cite_r(pkgs = "tidyverse")`.

This assumes there is a bib file of references called references.bib that contain the following entries.

  @Manual{r,
    title = {R: A Language and Environment for Statistical Computing},
    author = {{R Core Team}},
    organization = {R Foundation for Statistical Computing},
    address = {Vienna, Austria},
    year = {2021},
    url = {https://www.R-project.org/},
  }

  @Article{tidyverse,
    title = {Welcome to the {tidyverse}},
    author = {Hadley Wickham and Mara Averick and Jennifer Bryan and Winston Chang and Lucy D'Agostino McGowan and Romain François and #' Garrett Grolemund and Alex Hayes and Lionel Henry and Jim Hester and Max Kuhn and Thomas Lin Pedersen and Evan Miller and Stephan Milton #' Bache and Kirill Müller and Jeroen Ooms and David Robinson and Dana Paige Seidel and Vitalie Spinu and Kohske Takahashi and Davis #' Vaughan and Claus Wilke and Kara Woo and Hiroaki Yutani},
    year = {2019},
    journal = {Journal of Open Source Software},
    volume = {4},
    number = {43},
    pages = {1686},
    doi = {10.21105/joss.01686},
  }

Examples

# cite R and the tidyverse
cite_r(pkgs = "tidyverse")
#> [1] "R version 4.5.1 with the tidyverse (v2.0.0) package [@r; @tidyverse]"

# cite R and the tidyverse, but text only
cite_r(pkgs = "tidyverse", add_citations = FALSE)
#> R version 4.5.1 with the tidyverse (v2.0.0) package

# only cite R
cite_r(pkgs = NULL)
#> [1] "R version 4.5.1 [@r]"
