Not on Windows RGui, not without deeper magic, anyway (your examples
work quite happily in a terminal on Linux). If you can figure out how to
wire a Tcl channel to the R console, then I suppose it could be made to
work.
What might be easier to implement (currently it does not work) would be something like
tcl(cat, "Hello, World")
It almost works:
> .Tcl(paste(.Tcl.callback(cat), "foo\\n"))
foo
<Tcl>

..but apparently there is a discrepancy between the single-string return
value from .Tcl.callback(cat) and what .Tcl.objv expects.
