Also, I curious as to what a "slash over the R" (your original question) actually looks like. Do you mean it looks like an R with an acute accent over it? A grave acccent? A tilde? What *exactly*? You might like to try "grave R" or "acute R" in your Math formula. There's a list at < http://wiki.services.openoffice.org/wiki/Documentation/OOoAuthors_User_Manual/Writer_Guide/Math_commands_-_Reference> under "Attributes".
