That includes the full source code to shade3d. Like most generic
functions, it's a one-liner.
In the part of my post that you deleted, I told the OP where to look next.

UseMethod("shade3d")
I've observed this is possible in the
past, but now I can't remember how ...

The official way is to find the CRAN
package page and download the tar.gz
file and extract the files. Either
way, you get the whole package source
code this way.
I have a hunch this is the file you're
looking for
https://github.com/cran/rgl/blob/master/R/ashape3d.R
No, that's not it. That file works with mesh3d objects, but it has
nothing to do with arrows.

Remember, dealing with code on github is
just a small uptick from how Linux was
developed before, by shipping around
diffs and tarballs on a mailing list
much similar to this one, Thorvalds
merging them into the kernel in the
authoritarian way.
You can do it! *cheers*
Best,
Rasmus
