How to automatically create BibTex citations for R packages in knitr file?
I am not sure whether this an R, LaTeX, or BibTex problem.
I am trying to automatically generate a .bib file containing citations for R packages and then list them at the end. I am able to generate the BibTex file and I don't see anything wrong with the BibTex file, but the entries don't appear when I compile the PDF.
I'm not sure if R is not producing a BibTex file correctly, if some LaTeX syntax is wrong, or if the BibTex file needs to be pre-compiled or whatever. I noticed that bibliography{NOT A REAL FILENAME} will produce a References section without complaining, but I don't think that is the problem.
Minimal working example:
documentclass[10pt]{amsart}
usepackage[margin=1in, headheight=20pt, footskip=20pt]{geometry}
begin{document}
<<label='Create References'>>=
require(knitr) # Needed for write_bib()
# Load some packages to the session:
require(xtable)
require(ggplot2)
# Select packages to cite:
citPkgs <- names(sessionInfo()$otherPkgs)
# Write the bibtex file:
write_bib(citPkgs, file="R-Pckgs.bib")
@
nocite{*}
bibliographystyle{plain}
bibliography{R-Pckgs.bib}
end{document}
Any help or suggestions would be appreciated.
Just replace bibliography{R-Pckgs.bib} with bibliography{R-Pckgs} , and it should work fine.
On Windows 7, with an up-to-date MikTeX installation and current R and R packages, the following worked:
"eg.Rnw" and edit to remove the extraneous ".bib" "eg.Rnw" is located. library(knitr); knit2pdf("eg.Rnw") library(knitr); knit2pdf("eg.Rnw") Note: There are obviously many workflows for going from *.Rnw to *.pdf , but if you want to use knit2pdf() (at least), make sure that you run it from the directory containing the *.Rnw to be processed.
Add a nocite{dummycite} to your document - to create a citation so that the bibliography is printed.
Note that this is obsolete if you already have other citation in your document.
