Whilst in theory you could use Nikon lenses as the flange to mount distance is 47mm as opposed to the Nikon 46.5mm (and the Nikon's being larger than most of the other lens mounts, which is why it is so difficult to mount anything but Nikon on a Nikon body), the 0.5mm isn't enough for an adapter really.
There's adapters to mount the R lenses on F-mount though, the other way round, if that interests you.
Theres one on for £79 at the moment, it might be cheaper to just get this though for the adapter (and the lens a bonus):

Theres plenty of very nice Tamron Adaptall glass out there.
there is one original adapter for M lenses on R mount. from states, and around £70...am watching it and see what can be done![]()
That's probably an adapter to mount R lenses on a M body, you won't be able to focus past 50cm if you want to mount an M lens on to your R:
