I've written just such an interface. It ties proxy objects (subclassed from
data.frame) to postgres tables (it should be easy to write drivers for any
rdbms). The library needs a bit of cleaning up and documenting before I release
the package. I did run into some significant problems trying to subclass the
data.frame type, but I think they can be fixed (the current version knows nothing
about R internals).
