Dear Luis,
You might be interested in ?title. Here is an example took from ?image:
require(grDevices) # for colours
x <- y <- seq(-4*pi, 4*pi, len=27)
r <- sqrt(outer(x^2, y^2, "+"))
image(z = z <- cos(r^2)*exp(-r/6), col=gray((0:32)/32))
# title added after plotting
title(main="Here you go!")
Luis, take a look at the ?legend function, it can produce almost any kind of
legend you may need!
Hope It helps.
Rodrigo.

R-help,
I'm sorry that I said " I don't have idea ".
What I mean t is that I just don't know how to set a legend
when "image" is called.
Thanks in advance
