在分析数据时，我们需要引用R语言的特定版本，以及使用R包的版本，其实R语言中有代码可以调用，下面介绍一下。
1，引用R语言
在R语言中键入：
citation()结果：
> citation()To cite R in publications use:R Core Team (2022). R: A language and environment for statisticalcomputing. R Foundation for Statistical Computing, Vienna, Austria.URL https://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 = {2022},url = {https://www.R-project.org/},}We have invested a lot of time and effort in creating R, please cite itwhen using it for data analysis. See also ‘citation("pkgname")’ forciting R packages.里面有两种格式：
直接引用到出版物上：
R Core Team (2022). R: A language and environment for statisticalcomputing. R Foundation for Statistical Computing, Vienna, Austria.URL https://www.R-project.org/.如果是BibText的LaTex格式，可以用这种格式：
@Manual{,title = {R: A Language and Environment for Statistical Computing},author = {{R Core Team}},organization = {R Foundation for Statistical Computing},address = {Vienna, Austria},year = {2022},url = {https://www.R-project.org/},}各取所需。
2，引用R包
首先这个包是已经安装过的，比如ggplot2，可以写为：
citation("ggplot2")注意：需要放到双引号里面，否则会报错。
代码运行结果：
> citation("ggplot2")To cite ggplot2 in publications, please use:H. Wickham. ggplot2: Elegant Graphics for Data Analysis.Springer-Verlag New York, 2016.A BibTeX entry for LaTeX users is@Book{,author = {Hadley Wickham},title = {ggplot2: Elegant Graphics for Data Analysis},publisher = {Springer-Verlag New York},year = {2016},isbn = {978-3-319-24277-4},url = {https://ggplot2.tidyverse.org},}> 结果也是两种形式，一个是直接贴到文章中，一个是LaTex格式。
H. Wickham. ggplot2: Elegant Graphics for Data Analysis.Springer-Verlag New York, 2016.3，更灵活的方法
使用R包：pacman，里面的函数比较灵活，有：
- p_cite
- p_citation
它的优点R包不用双引号包裹，更灵活。
R包引用：
pacman::p_cite()> pacman::p_cite()sh: xclip: command not foundTo cite R in publications use:R Core Team (2022). R: A language and environment for statisticalcomputing. R Foundation for Statistical Computing, Vienna, Austria.URL https://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 = {2022},url = {https://www.R-project.org/},}We have invested a lot of time and effort in creating R, please cite itwhen using it for data analysis. See also ‘citation("pkgname")’ forciting R packages.也可以：
pacman::p_citation()> pacman::p_citation()sh: xclip: command not foundTo cite R in publications use:R Core Team (2022). R: A language and environment for statisticalcomputing. R Foundation for Statistical Computing, Vienna, Austria.URL https://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 = {2022},url = {https://www.R-project.org/},}We have invested a lot of time and effort in creating R, please cite itwhen using it for data analysis. See also ‘citation("pkgname")’ forciting R packages.引用R包：
pacman::p_cite(ggplot2)> pacman::p_cite(ggplot2)sh: xclip: command not foundTo cite ggplot2 in publications, please use:H. Wickham. ggplot2: Elegant Graphics for Data Analysis.Springer-Verlag New York, 2016.A BibTeX entry for LaTeX users is@Book{,author = {Hadley Wickham},title = {ggplot2: Elegant Graphics for Data Analysis},publisher = {Springer-Verlag New York},year = {2016},isbn = {978-3-319-24277-4},url = {https://ggplot2.tidyverse.org},}这样就不用担心引用R语言和R包了。
