R: Bibliography Entries

bibentry {utils} | R Documentation

## Bibliography Entries

### Description

Functionality for representing and manipulating bibliographic information in enhanced BibTeX style.

### Usage

    bibentry(bibtype, textVersion = NULL, header = NULL, footer = NULL,
             key = NULL, ..., other = list(),
             mheader = NULL, mfooter = NULL)
    ## S3 method for class 'bibentry'
    print(x, style = "text", .bibstyle, ...)

### Arguments

`bibtype` | a character string with a BibTeX entry type. See Entry Types for details.
`textVersion` | a character string with a text representation of the reference to optionally be employed for printing.
`header` | a character string with optional header text.
`footer` | a character string with optional footer text.
`key` | a character string giving the citation key for the entry.
`...` | for `bibentry`: arguments of the form `tag=value` giving the fields of the entry, with tag and value the name and value of the field, respectively. Arguments with empty values are dropped. See Entry Fields for details. For the `print` method, extra parameters to pass to the renderer.
`other` | a list of arguments as in `...` (useful in particular for fields named the same as formals of `bibentry`).
`mheader` | a character string with optional “outer” header text.
`mfooter` | a character string with optional “outer” footer text.
`x` | an object inheriting from class `"bibentry"`.
`style` | an optional character string specifying the print style. If present, must be a unique abbreviation (with case ignored) of the available styles, see Details.
`.bibstyle` | a character string naming a bibliography style.

### Details

The bibentry objects created by `bibentry` can represent an arbitrary positive number of references. One can use `c()` to combine bibentry objects, and hence in particular build a multiple reference object from single reference ones. Alternatively, one can use `bibentry` to directly create a multiple reference object by “vectorizing” the given arguments, i.e., use character vectors instead of character strings.

The `print` method for bibentry objects provides a choice between seven different styles: plain text (style `"text"`), BibTeX (`"Bibtex"`), a mixture of plain text and BibTeX as traditionally used for citations (`"citation"`), HTML (`"html"`), LaTeX (`"latex"`), R code (`"R"`), and a simple copy of the `textVersion` elements (style `"textVersion"`). The `"text"`, `"html"` and `"latex"` styles make use of the `.bibstyle` argument using the `bibstyle` function. When printing bibentry objects in citation style, a `header`/`footer` for each item can be displayed as well as a `mheader`/`mfooter` for the whole vector of references.

The `print` method is based on a `format` method which provides the same styles, and for formatting as R code a choice between giving a character vector with one `bibentry()` call for each bibentry (as commonly used in ‘CITATION’ files), or a character string with one collapsed call, obtained by combining the individual calls with `c()` if there is more than one bibentry. This can be controlled by setting the option `collapse` to `FALSE` (default) or `TRUE`, respectively. (Printing in R style always collapses to a single call.) Further, for the `"citation"` style, `format()`'s optional argument `citation.bibtex.max` (with default `getOption("citation.bibtex.max")` which defaults to 1) determines for up to how many citation bibentries text style is shown together with with bibtex, automatically.

It is possible to subscript bibentry objects by their keys (which are used for character subscripts if the names are `NULL`).

There is also a `toBibtex` method for direct conversion to BibTeX.

### Value

`bibentry` produces an object of class `"bibentry"`.

### Entry Types

`bibentry` creates `"bibentry"` objects, which are modeled after BibTeX entries. The entry should be a valid BibTeX entry type, e.g.,

Article:

  An article from a journal or magazine.

Book:

  A book with an explicit publisher.

InBook:

  A part of a book, which may be a chapter (or section or whatever) and/or a range of pages.

InCollection:

  A part of a book having its own title.

InProceedings:

  An article in a conference proceedings.

Manual:

  Technical documentation like a software manual.

MastersThesis:

  A Master's thesis.

Misc:

  Use this type when nothing else fits.

PhdThesis:

  A PhD thesis.

Proceedings:

  The proceedings of a conference.

TechReport:

  A report published by a school or other institution, usually numbered within a series.

Unpublished:

  A document having an author and title, but not formally published.

### Entry Fields

The `...` argument of `bibentry` can be any number of BibTeX fields, including

address:

  The address of the publisher or other type of institution.

author:

  The name(s) of the author(s), either as a character string in the format described in the LaTeX book, or a `person` object.

booktitle:

  Title of a book, part of which is being cited.

chapter:

  A chapter (or section or whatever) number.

editor:

  Name(s) of editor(s), same format as `author`.

institution:

  The publishing institution of a technical report.

journal:

  A journal name.

note:

  Any additional information that can help the reader. The first word should be capitalized.

number:

  The number of a journal, magazine, technical report, or of a work in a series.

pages:

  One or more page numbers or range of numbers.

publisher:

  The publisher's name.

school:

  The name of the school where a thesis was written.

series:

  The name of a series or set of books.

title:

  The work's title.
