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) ?
No functions for that. You just need to give the letters in lowercase
or uppercase: lowercase is phi, uppercase is Phi. Run
demo(plotmath) for more hints.
