Hello, well, I searched list-archive, cran and the references, but found nothing. Thus: Does anybody around here know anything about Dempster-Shafer Theory, Evidence Theory or Hints in R? Has anybody stumbled about a package that I overlooked or implemented something in this area? I really would like to not implement a hint-model a second time. My apologies if I missed something obvious, but I would be glad if someone could give me a hint.

It has been heavily discussed and criticized, and it was considered by many as statistically unsound. This might be the reason why it has not been realized in an R package. As a scheme for reasoning under uncertainty Dempster-Shafer Theory has been replaced by Bayesian Networks and their learning capabilities in many modern knowledge-based systems. Fortunately, there are several packages in R that implement Bayesian statistics and networks, including learning facilities. You will find references in the 'Bayesian' and 'Machine Learning' task views.
