[R] Simultaneous subscripts and superscripts

Dear List,

I'd like to add text to a plot where a text symbol has both a 
superscript and subscript.  For example, the variable S with a 
superscript 2 and a subscript t.  I have been able to accomplish this 
using either

expression( paste(S,atop(scriptstyle(2),scriptstyle(t))) )


expression( {S[t]}^2 )

but the spacing isn't quite right (or rather what I'd like) using 
either of these.  By 'right' I mean the placement and spacing don't 
quite coincide with what I'd expect if I superimposed S^2 with S[t]. 
Is there a way to place BOTH a subscript and superscript so that they 
are placed identically as if I had overlayed S^2 and S[t]?

I'm using R 1.9.0 on Mac OSX.
