R “stats” citation for a scientific paper

Question

I analyzed my data using R package ‘stats’ (version 2.15.3). A reviewer asked me the right citation of this package and not only the common

R Core Team (2012). R: A language and environment for statistical computing. R Foundation for Statistical Computing, Vienna, Austria. ISBN 3-900051-07-0, URL http://www.R-project.org/

Anyone know where i can find a valid citation to insert in my paper? Thanks

Answer 1

In our recent book, my co-author and I did the R citation (in the frontmatter) but also got the publisher to let us give per-package credit as well:

We felt that it was important to ensure those that did the work got credit all the way 'round.

(I wld have made this only a comment, but can't easily embed pix that way and rly didn't want to host the img somewhere.)

Answer 2

The reviewer is wrong:

 citation("stats")

The ‘stats’ package is part of R.  To cite R in publications use:

  R Core Team (2013). R: A language and environment for statistical computing. R
  Foundation for Statistical Computing, Vienna, Austria. ISBN 3-900051-07-0, URL
  http://www.R-project.org/.

A BibTeX entry for LaTeX users is

  @Manual{,
    title = {R: A Language and Environment for Statistical Computing},
    author = {{R Core Team}},
    organization = {R Foundation for Statistical Computing},
    address = {Vienna, Austria},
    year = {2013},
    note = {{ISBN} 3-900051-07-0},
    url = {http://www.R-project.org/},
  }

We have invested a lot of time and effort in creating R, please cite it when
using it for data analysis. See also ‘citation("pkgname")’ for citing R
packages.

Answer 3

There is now a grateful package that can be handy:

The goal of grateful is to make it very easy to cite the R packages used in any report or publication. By calling a single function, it will scan the project for R packages used and generate a document with citations in the desired output format (Word, PDF, HTML, Markdown). Importantly, these references can be formatted for a specific journal so that we can just paste them directly into the bibliography list of our manuscript or report.

https://github.com/Pakillo/grateful

If the package stats is loaded, the reference can be obtained by running:

library(grateful)
cite_packages()

—assuming grateful has already been installed by running:

library(devtools)
install_github("Pakillo/grateful")

Answer 4

As hrbrmstr pointed out, a function to create a list of references of only loaded packages would come in handy. As he only showed us an example and not the function, I wrote one myself which I use very often in scientific analyses and papers (sometimes combined with R Markdown).

citations <- function(includeURL = TRUE, includeRStudio = TRUE) {
    if(includeRStudio == TRUE) {
        ref.rstudio <- RStudio.Version()$citation
        if(includeURL == FALSE) {
            ref.rstudio$url = NULL;
        }
        print(ref.rstudio, style = 'text')
        cat('\n')
    }

    cit.list <- c('base', names(sessionInfo()$otherPkgs))
    for(i in 1:length(cit.list)) {
        ref <- citation(cit.list[i])
        if(includeURL == FALSE) {
            ref$url = NULL;
        }
        print(ref, style = 'text')
        cat('\n')
    }
}

So, for example, after running

library(readr)
library(dplyr)
library(ggplot2)
library(knitr)

the function citations() will print:
