An experimental package, based on protoClasses, that implements a micro language for developing Bayesian models in R. It aims to be as general as BUGS, vectorized and fully integrated with R. The model definition and manipulation is done at the level of plate templates (prototypes) instead of basic nodes as in BUGS.

It's not yet useful for anyone except me, but I've recently resumed working on it, and hope to make it alive very soon now.
