I feel this becomes a frequently asked question, hence I tried Google
and typed "R main expression greek" --- and got an answer:

Dear r-help list,
I am trying to combine a greek letter lambda with the contents of a variable v
in the title of a plot. However, it seems that having v inside the expression()
function causes it not to be evaluated, on the other hand having
expression(lambda) inside something else like paste causes it to be evaluated
to a string. Here is an example of what I want to do:
title(main=expression("Value of "*Lambda*paste(" = ",v,sep="")))
Is there any solution for this?
Cheers,
Ingeborg Schmidt
