I have a counterexample to your claim that ggplot2 does not support
superscript or subscript formatting in the title :)
df <- data.frame(u = (1:10)^2, v = exp(seq(0, 4.5, by = 0.5)))
g <- ggplot(df, aes(u, v))
g + geom_point() + opts(title = expression(x[1]^2~~'and'~~e^y))
g + geom_point() + opts(title = expression(x[1]^2~~'and'~~e^y)) +
xlab(expression(x[1]^2)) + ylab(expression(e^y))
...unless I'm misunderstanding what you mean by 'formatting' subscripts and
superscripts. If so, some elaboration of the problem would be helpful.
HTH,
