Hi Stefan,

This is interesting, and timely because it interacts with what we're thinking
about with the image library. I gather this is R-like, and I've not used R, so
I can't comment as fully as others surely can.

I'd add:
That controls what gets put in place of an NA when you construct the object. I
suspect one want it to be 0 in most cases, but might as well make it flexible.

The rest seems reasonable to me, with the caveat that I don't know what a
DataFrame is.
