I don't think that there is a way other than calling citation() for each
of the installed.packages(). You could do something like this:
## try to get BibTeX for each of the installed packages
b <- lapply(installed.packages()[,1], function(x)
try(toBibtex(citation(x))))
## omit failed citation calls
b <- b[-which(sapply(b, class) == "try-error")]
## unify to list of Bibtex
b <- lapply(b, function(x) if(inherits(x, "Bibtex")) list(x) else
x)
## list of unique entries
b <- unique(do.call("c", b))
## write everything to a single .bib file
writeLines(do.call("c", lapply(b, as.character)),
"Rpackages.bib")
