[R] scalable < > delimiters in plotmath

Dear list,

I read in ?plotmath that I can use bgroup to draw scalable delimiters
such as [ ] and ( ). The same technique fails with < > however, and I
cannot find a workaround,

grid.text(expression(bgroup("<",atop(x,y),">")))

Error in bgroup("<", atop(x, y), ">") : invalid group delimiter

Regards,

baptiste
