Description

Upon a little experimentation, it seems the only thing preventing a big.matrix from the bigmemory package to be used as a Seed inside a DelayedArray is that dim() on a big.matrix returns a numeric and not an integer. This is caught by the check in extract_array() raising an error.

Would it be possible to relax this check to accept numeric as well as integer? Many on-disk matrix packages return numeric via dim() (bigmemory, filematrix, feather, fst, etc). It seems inconvenient to have to define a new Seed class for these packages just to reimplement the simple dim() function.
