I cannot see any slashed examples of "R" on your given page. We are
floundering a bit here and either need a graphical example or a better
description. I can find no examples of any R being crossed in any way on the
Internet after searching "binary relational mathematics" and reading till my
brain hurt. One _singular_ visual example would suffice. At a guess i would
say you are looking for something like a diagonal slash across a capital R by
your decription but this has not been made clear. AFAIK, options in OO.o are:
"acute{R} bar{R} breve{R} check{R} circle{R} dddot{R} ddot{R} dot{R} grave{R}
hat{R} overline{R} overstrike{R} tilde{R} vec{R} widehat{R} widetilde{R}
widevec{R} setr" all of which work on my version. You are welcome to copy and
paste and see if any of these work for your purpose.
If this is not acceptable then realise that the equation editor in Microsoft
Office is a cut-down version of the stand-alone specialist tool MathType by
DesignScience and that MathType allows you to cut and paste to OO.o or Office
among others. Neither Ofice nor OO.o as "general office productivity
suites"TM are designed to suit every niche market.
