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))) )
or
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.
Thanks,
Brian

expression(S[t]^2) looks pretty good for me (on windows()). Andy> From: Brian Beckage > > Dear List, > > I'd like to add text to a plot where a text symbol has both a > superscript and subscript.

If letters don't have the same width, it is difficult to calculate pretty bounding boxes ... and the expected behaviour is to left-align. Hence it's as expected. Are you volunteering to add some fuzz to plotmath.c? I guess you will have to add quite a lot of code for this tiny step... (and R is not TeX, BTW). Uwe Ligges

I guess it's good to type what makes sense: I can understand squaring S[t], but it's hard for me to fathom subscripting S^2...> -----Original Message----- > From: Brian Beckage [mailto:Brian.Beckage at uvm.edu] > Sent: Monday, August 09, 2004 1:55 PM > To: Liaw, Andy; r-help at stat.math.ethz.ch > Subject: RE: [R] Simultaneous subscripts and superscripts > > > Yep, it looks good on my system as well.
