R devel - Oct 2010 - args() and body() equivalents for S4 methods?

Dear list,

Suppose some methods were defined for a generic function genF(fitobj,
...).  Suppose one has signature(fitobj="lm") and
signature(fitobj="glm").  The ... piece of each method could have
different arguments.  I'm aware of getMethod("genF",
"lm") to get the
function definition but are there equivalents to the args() and body()
functions?

Thanks.
Vinh

Thanks Professor Lumley, this is sufficient.
