BUGS is more than just one program (created 2010-11-19)
This page is moving to a new website.
GeoBUGS is a specialized add-on for BUGS that fits spatial models. It was
developed by the Department of Epidemiology and Public Health of Imperial
College at St Mary's Hospital London. The main page for GeoBUGS is
PKBugs is another specialized add-on for BUGS. This one fits
pharmacokinetic models. It was developed by Dave Lunn when at the Department
of Epidemiology and Public Health of Imperial College at St Mary's Hospital
London. The main page for PKBugs is
OpenBUGS is an open source and platform independent version of BUGS. It was
developed by Andrew Thomas at the Rolf Nevanlinna Institute of the University
of Helsinki. The current version is 3.1.2. Many sites link to the earlier

There are some problems with porting OpenBUGS, so a competing program,
JAGS, was developed that is more easily compiled under a variety of operating
systems. It was developed and is currently being maintained by Martyn Plummer.
The current version is 2.1.0. The main page for JAGS is
You can run BUGS programs within R using one of two packages: BRugs or
R2WinBUGS. BRugs can run both WinBUGS and OpenBUGS. Unfortunately, it does not
work with the 64-bit Windows version of R, so it has been removed from the

Sigh, again. Maybe I'll install a 32 bit version of R.
Wikipedia has a nice series of brief articles about these programs:
