[R] Can I increase the size of an asterisk in plotmath()?

[Rolf Turner]

I am trying to plot an expression of the form "p^*" --- a bold letter p 
with the asterisk as a superscript.

I can get *something* with code of the form

plot(1:10)
text(7.5,2.5,expression(paste(bolditalic(p)^"*")))

but the asterisk that appears is *tiny*.

Is there any way to increase its size?  (I expect not, but I just 
thought I'd ask!)

cheers,

Rolf Turner
