I have a simple (!) problem.  What I want to do is to create a legend with
Greek letters, and substituting numbers into the legend. Like this:

mu=1:3
Mean=rep(mu, each=20)
plot(runif(60), rnorm(60,Mean,0.1), pch=Mean) # create a plot
 legend(0.6,1.7, paste("mu =", 1:3), pch=mu)

but with a Greek letter mu.

I think the solution has something to do with substitute() possibly along
with and eval(), paste() and probably a few other functions.  But the help
page is remarkably unhelpful: it seems to have been written for people who
work with the underlying code, and not for us mere mortals.  Could someone
explain how to do this?
