Explicit @backref tag

[krlmlr]

... systems like Rcpp could use it to point you back to the original source location. (Reference)

What should be the semantics? Should it override the autogenerated source references? What should be the output?

[hadley]

Yes, it would just override the autogenerated reference. It would output the same thing as the autogenerated.

Can we close this now? This would be the same as @source, right?

[krlmlr]

I'm not sure -- @source shows in the generated .Rd files (as \source{...}), whereas @backref was intended to show only in the comment in the header. I think this is a useful feature and easy enough to add, I can take a look. (Is there a CRAN release in sight?)

[hadley]

Oops, I think I got confused with source, and what you implemented. Did you add an explicit tag?

I'm preparing for a release by the end of the week (mostly because it fixes a bug with dev stringr)
