How can I access the C++ source associated with the rgl function shade3d. More
specifically, I'm interested in the part of the code used by arrow3d to draw
arrow heads.
I'm not familiar with how GitHub is organized and I've put in a lot of effort
doing searches there and on the web in general.
I'm struggling to come up to speed with rgl. At the moment, I'm struggling with
the function arrows3d(). In the R documentation for that, two
parameters/arguments are mentioned: "thickness" (of the arrow's shaft) and
"width" (of the arrow's shaft).
Naively, I would expect the arrow's shaft unde
blems. I've been planning to do that in the near future anyway.
Thanks in advance for any help.

After an unsuccessful search thru several books plus online documentation, I
was unable to find a simple way to do this, so I wrote my own function (see
below) to do it. I'm relatively new to R however, so I'm guessing that there
must be an easier way to do it.

Due to convention a script "l" - $$\ell$$ (LaTeX \ell) is used to represent a
certain quantity in something I'm working on. I'm unable to figure out how to
use it in R. It's not included in the list on ?plotmath.
Can anyone tell me how to use it? Its unicode is U+2113. This page has a list
