It will once you execute

rc.settings(files = TRUE)

in R (I do so in my .Rprofile). Filename completion is turned off by
default because Emacs does it's own filename completion. In the *R*
buffer, TAB is bound to the native filename completion when the cursor
is inside quotes, but that's not true in .R file buffers.

You can still activate the native filename completion using M-TAB
(Alt-TAB will usually be captured by the Window manager, but Esc TAB
should work).
