Feature Request: A function to provide all files that will be loaded

[billdenney]

I'm working to incorporate drake in more of my workflows, and one thing that it does well is track files outside of R in the dependencies for results.

As described in ropensci/drake#721, it would help to make these dependent files known to drake. Is there a way to know in advance all the files that will be loaded by xpose_data() (or as this is a feature request, I think the question is "could there please be a way...")?

@billdenney very good suggestion I am also looking into drake myself I would certainly like to see xpose compatible with it !!

FYI, drake can now have all files in a directory as a dependency. If you do file_in() with a directory name, it will include all files in the directory. Also, as I’ve learned, drake’s file handling is more static, so I don’t know that this will work directly with drake right now.

(I still think that there is value in this feature, but it won’t work in drake due to limitations on that side right now. When dynamic branching is achieved over there, it will probably be useful in a drake context.)
