## Citing R and R Packages in Publications

### Description

How to cite R and R packages in publications.

### Usage

    citation(package = "base", lib.loc = NULL)
    ## S3 method for class 'citation':
    toBibtex(object, ...)
    ## S3 method for class 'citationList':
    toBibtex(object, ...)

### Arguments

`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.

### Details

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 analysis.

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).

### Value

An object of class `"citationList"`.

### See Also

`citEntry`

### Examples

    ## 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)
