Nobody has mentioned Julia. Last year Changcheng Li did a Google Summer of Code project to add automatic differentiation capability to R. autodiffR package was result, but it is still "beta". The main awkwardness, as I would guess for Wolfram and other wrappings, is the non-R side having "updates" so the interface changes slightly but enough to force changes in the wrapper.
As Jeff points out, those with itch must be the scratchers. JN On 2019-07-06 7:15 a.m., Jeff Newmiller wrote: > I don't get it.
