bibentry: 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)
"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.

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.

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Unpublished:: A document having an author and title, but not formally published.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.
doi:: The DOI (https://en.wikipedia.org/wiki/Digital_Object_Identifier) for the reference.
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.
url:: A URL for the reference. (If the URL is an expanded DOI, we recommend to use the doi field with the unexpanded DOI instead.)
volume:: The volume of a journal or multi-volume book.
year:: The year of publication.

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.

Examples

Run this code

## R reference
rref <- bibentry(
   bibtype = "Manual",
   title = "R: A Language and Environment for Statistical Computing",
   author = person("R Core Team"),
   organization = "R Foundation for Statistical Computing",
   address = "Vienna, Austria",
   year = 2014,
   url = "https://www.R-project.org/")

## Different printing styles
print(rref)
print(rref, style = "Bibtex")
print(rref, style = "citation")
print(rref, style = "html")
print(rref, style = "latex")
print(rref, style = "R")

## References for boot package and associated book
bref <- c(
   bibentry(
     bibtype = "Manual",
     title = "boot: Bootstrap R (S-PLUS) Functions",
     author = c(
       person("Angelo", "Canty", role = "aut",
         comment = "S original"),
       person(c("Brian", "D."), "Ripley", role = c("aut", "trl", "cre"),
         comment = "R port, author of parallel support",
         email = "ripley@stats.ox.ac.uk")
     ),
     year = "2012",
     note = "R package version 1.3-4",
     url = "https://CRAN.R-project.org/package=boot",
     key = "boot-package"
   ),

   bibentry(
     bibtype = "Book",
     title = "Bootstrap Methods and Their Applications",
     author = as.person("Anthony C. Davison [aut], David V. Hinkley [aut]"),
     year = "1997",
     publisher = "Cambridge University Press",
     address = "Cambridge",
     isbn = "0-521-57391-2",
     url = "http://statwww.epfl.ch/davison/BMA/",
     key = "boot-book"
   )
)

## Combining and subsetting
c(rref, bref)
bref[2]
bref["boot-book"]

## Extracting fields
bref$author
bref[1]$author
bref[1]$author[2]$email

## Convert to BibTeX
toBibtex(bref)

## Format in R style
## One bibentry() call for each bibentry:
writeLines(paste(format(bref, "R"), collapse = "\n\n"))
## One collapsed call:
writeLines(format(bref, "R", collapse = TRUE))
