⚠️There's a newer version (0.9-2.1) of this package.Take me there.

BRugs (version 0.8-1)

R interface to the OpenBUGS MCMC software

Description

Fully-interactive R interface to the OpenBUGS software for Bayesian analysis using MCMC sampling. Runs natively and stably in 32-bit R under Windows. Versions running on Linux and on 64-bit R under Windows are in "beta" status and less efficient.
