R help - Jan 2008 - titles with superscript and variale value

Hi everyone,


I am trying to write a title for a plot which has a superscript like D^2 and a
value of a variable stored in that variable..... i am not sure if i am clear so
i will try an example:


 Suppose i want my title to be like: Family: Gaussian; D^2 = 0.45


 where i have the value 0.45 stored in variable d2 (which comes from some
previous calculations, and depending which actual variables i am plotting, this
d2 can have different values), and i want D^2 to be D superscrip 2.


 I've tried the following command lines:

> title(main = expression(paste( "Family: Gaussian; ", D^2, "
= ", d2)))

 which gives me the right superscript but instead of the value stored in d2 i
get actually "d2" .... or

> title(main = paste("Family: Gaussian; ", expression(D^2), "
= ",d2))

 which gives me the real value stored in d2 but no superscript for D .... it
comes like D^2 instead.


 I've tried few other command lines  more foolish than the ones above ....
with no result. I will really appreciate if you have any suggestions to get this
title right.


 Thanks,


 Monica

Try this

plot(rnorm(100), main=bquote(Family ~ Gaussian ~ ";" ~ D^2 == .(d2)))
