[R] Documenting a function: How to get the comments in a function similar to args()

[stephen sefick]

What are the comments line at the beginning of the function?  if you
just type in the function name then you get the code, and it seems
that R removes the comment lines to make the code more readable.  I
just looked at a function in a package that I created and know that
there are comments in there.  If you need the comments I would look in
the source package.  I believe that if you go to the folder where
packages are installed then you can get to the sorces.  I think this
is what you want.

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods. We are mammals, and have not exhausted the
annoying little problems of being mammals.
