Hi all, I want to present a figure including the uppercase and lowercase version of the greek letter phi. I know that I can use "expression" to have the symbol like in: plot(1~1, main = expression(phi)) But, is there somewhere things like upper(phi) or lower(phi) ? Thanks for your help !

You just need to give the letters in lowercase or uppercase: lowercase is phi, uppercase is Phi. Run demo(plotmath) for more hints. Duncan Murdoch
