R help - Oct 1999 - greek letters and deparsing in title

Dear All,

In the title of a plot, I would like to mix greek letters with numbers, where
the numbers are obtained from a particular function to a vector (e.g., max(x));
in each call, the value of this vector can change.

Without greek symbols I use something like:
title(sub=paste("x1=", deparse(x[1]),"beta =
",deparse(max(x)), "rho = ",
deparse(min(x)))) 

but I'd like beta and rho to show up as greek letters.

I have tried several combinations of "expression", "paste",
"plain", and looked
at the help for legend, text, and title, but I am not able to get it to work.

Thank you,

Ramon

Try eg
R> x<-rnorm(100)
R> plot(x,main=substitute(beta==t,list(t=max(x))))
