Robin,
Rcpp is experimenting with a 'callback' scheme in vignettes.
For this, Rcpp itself has an unexported function bib() defined as
bib <- function() {
sub("\\.bib$", "", system.file( "doc", "Rcpp.bib", package = "Rcpp" ) )
}
and packages depending on Rcpp can then do this in the vignette header:
RcppBibfile <- sub("\\.bib$", "", Rcpp:::bib())
which gets used towards the end of the Rnw file as
\bibliography{\Sexpr{RcppBibfile}}
I think so far only one package is using it.
Hth, Dirk
