It's been a while since I proposed syrfr and I have been constantly in contact with the many people in the R community and I wasn't able to find a mentor for the project. I later got interested in the Automatic Differentiation proposal (adinr) and, on consulting with a few others within the R community, I mailed John Nash (who proposed adinr in the first place) if he'd be willing to take me up on the project. I got a positive reply only a few hours ago and it was my mistake to have not removed the syrfr proposal in time from the wiki, as being listed under proposals looking for mentors.
While I appreciate your interest in the syrfr proposal I am afraid my allegiances have shifted towards the adinr proposal, as I got convinced that it might interest a larger group of people and it has wider scope in general. I apologize for having caused this trouble.
