Yes. The source code for that function sits inside #ifndef Win32, so
it's hardly a bug, except that the documentation might be clearer (or
the R wrapper could throw a more explicit error). The whole thing is
quite experimental, on Unix too -- really just a proof of concept
thing at present.
The fundamental issue is that the way Tk takes over R's event loop
involves redefining ptr_R_ReadConsole and friends. This is quite
Unix-specific and the relevant declarations are lifted from
src/unix/devUI.h.
I don't know what the equivalent would be on Windows (a platform I use
reluctantly myself), and I kind of suspect that it can only work from
Rterm, not Rgui. Contributions from knowledgeable Windows programmers
would be welcome.
