[R] How to see how a function is written

Erik, I see the following when I type "apply" at the prompt:

> apply
standardGeneric for "apply" defined from package "base"

function (X, MARGIN, FUN, ...)
<environment: 0x03cad7d0>
Methods may be defined for arguments: X, MARGIN, FUN
Use  showMethods("apply")  for currently available ones.

Also, whether I type "mean" at the prompt, or I type "edit(mean)", I
do not see the underlying code for function "mean". How would I be
able to see it?

My machine:
platform       i386-pc-mingw32
arch           i386
os             mingw32
system         i386, mingw32
major          2
minor          10.1
year           2009
month          12
day            14
svn rev        50720
language       R
version.string R version 2.10.1 (2009-12-14)
