I wrote the Notation package that ships with Mathematica 3.0. It will allow
you to easily do this. There is a demonstration of the package under the
help browser Demos -> Notation Maker.

You load the package with <<Utilities`Notation`

Just see the documentation and you will see how to symbolize R\_x Then it
is a simple matter to use this in a definition e.g.

\!\(f[R\_x : _] := g[R\_x]\)

You really need WYSIWYG email to read this :) but just paste it into
Mathematica and it looks nice.

There is an update to the Notation package which is about to be announced
by me at (The code is complete but
the documentation might change a little.)
