I said the same in 2012:

This was the reply then, too. Basically, the org header arguments manual page mentions that language-specific arguments are on the appropriate page in worg babel. If you click that link, then the link to the lust of supported languages, that gets you to a table and to ob-doc-R.

Maybe not ideal, but I think the intent is not to clutter the manual with every  specific arg possible. Sorry it was confusing.

For changes, there's good info on worg about editing and pushing to worg, which is on git. The manual requires patching, but that's documented as well.
