[R] varphi symbol for ylab expression

Hi all,

it is possible to invoke certain graphical functions (e.g. curve)
with an expression argument, e.g. "ylab=expression(phi)". There are
some greek letters with a second script. For instance, in latex
two symbols do exist: phi and varphi. Is the second symbol also 
available in an expression()? If yes, how?

Kind regards,
