How to automatically create BibTex citations for R packages in knitr file?

Question

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 th

Answer 1

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:

1. Put your reproducible example in a file named "eg.Rnw" and edit to remove the extraneous ".bib"
2. Launch R and navigate to the directory in which "eg.Rnw" is located.
3. Do 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.

Answer 2

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Note that this is obsolete if you already have other citation in your document.
