trueskill: Implementation the TrueSkill algorithm in R

An implementation of the TrueSkill algorithm (Herbrich, R., Minka, T. and Grapel, T) in R; a Bayesian skill rating system with inference by approximate message passing on a factor graph. Used by Xbox to rank gamers and identify appropriate matches. Current version allows for one player per team. Will update as time permits. Requires R version 3.0 as it is written with Reference Classes. URL: Acknowledgements to Doug Zongker and Heungsub Lee for their python implementations of the algorithm and for the liberal reuse of Doug's code comments (@dougz and @sublee on github).
