How to cite R and R packages in publications.
citation(package = "base", lib.loc = NULL) ## S3 method for class 'citation': toBibtex(object, ...) ## S3 method for class 'citationList': toBibtex(object, ...)
package |
a character string with the name of a single package. An error occurs if more than one package name is given. |
lib.loc |
a character vector with path names of R libraries, or
NULL. The default value of NULL corresponds to all
libraries currently known. If the default is used, the loaded
packages are searched before the libraries. |
object |
return object of citation. |
... |
currently not used. |
The R core development team and the very active community of package authors have invested a lot of time and effort in creating R as it is today. Please give credit where credit is due and cite R and R packages when you use them for data anlysis.
Execute function citation() for information on how to cite the
base R system in publications. If the name of a non-base package is
given, the function
either returns the information contained in the CITATION
file of the package or auto-generates citation information. In the
latter case the package ‘DESCRIPTION’ file is parsed, the
resulting citation object may be arbitrarily bad, but is quite useful
(at least as a starting point) in most cases.
If only one reference is given, the print method shows both a text
version and a BibTeX entry for it, if a package has more than one
reference then only the text versions are shown. The BibTeX versions
can be obtained using function toBibtex (see the examples below).
An object of class "citationList".
## the basic R reference
citation()
## references for a package -- might not have these installed
if(nchar(system.file(package="lattice"))) citation("lattice")
if(nchar(system.file(package="foreign"))) citation("foreign")
## extract the bibtex entry from the return value
x <- citation()
toBibtex(x)
