You just need to put the '>=' inside an expression.  For example, try ...

    plot(1, type="n")
    text(1,1,expression(x >= y))

More generally, the command 'example(plotmath)' produces several tables of
the commands required to produce the possible sorts of mathematical
annotation (it is important to type 'par(ask=T)' first so that you can pause
on each table).  The mathematical annotation facilities are also described
in a recent journal article ...

     mathematical annotation in plots. Journal of Computational and
     Graphical Statistics, 9, 582-599.

Hope that helps :)
