In my defence, I did also write a chapter on the C API:
https://github.com/hadley/devtools/wiki/c-interface, and I think
arcane is the right word to describe it! There's a lot of historical
baggage in the API, and most things are not named the same way as in R
(eg. real instead of numeric, VECSXP vs LISTSXP, namesgets to _set_
names, ...)

You're welcome, and any feedback will be greatly appreciated.
