cleaner/shorter citation calls by key?

[cboettig]

A quick idea that came in my mind is, use deparse() or as.list(match.call()[-1]) inside citep() so that you can get rid of quotes, then use the dot-dot-dot argument; finally you should be able to write citep(Halper2006, Xie2012) - Yihui

[cboettig]

In other words, stick something like this at the start of citep.

> f <- function(...){ L <- as.list(match.call()[-1]); sapply(L, deparse)}
> f(Halpern2006, Xie2012)
[1] "Halpern2006" "Xie2012"

• Will have to do the sapply only if the items given are not named?
• DOIs will need quotations.
• Calls in format citep(name="10.11", name2 = "10.12) will work, but not calls in the original format citep(c(name="10.11", name2 = "10.12"))
• Cannot pass in bibentry objects at all, only names. Will have to write the whole bib in advance and then just use keys?

[cboettig]

Unlikely to be able to drop the quotations in the call and always parse successfully, particularly now that other data can be added to the citet call, such as the CiTO reason.

Meanwhile, at least the same interface will take a DOI, a bibentry object, a URL, or a character string matching a bibkey, and bibkeys can be assigned at the time of call.
