I got a new computer via a project. It is a Windows machine which is heavily administered, but they let me put Virtualbox on it, and naturally I have Ubuntu running on it so I can actually build the tools that let me do work. Times like this I am very glad I've been putting my installation notes for various packages on the blog since it saves me time searching all over the place (e.g. some gotchas on Eclipse and StatET (R-project))
For JAGS (Just Another Gibbs Sampler), there is an Ubuntu package of 1.0.2, but JAGS is at 2.0+. And the CRAN packages of rjags and R2jags are similarly behind. So I downloaded the source and installed them.
JAGS was simple. The usual combination of:
sudo make install
works as expected.
For rjags and R2jags I had to try a number of different configurations. I ended up with
sudo R --with-jags-modules=/usr/local/lib/JAGS/modules-2.1.0 CMD INSTALL rjags_2.1.0-10.tar.gz
sudo R --with-jags-modules=/usr/local/lib/JAGS/modules-2.1.0 CMD INSTALL R2jags_0.02-09.tar.gz
While I'm not entirely sure that sudo was necessary, prior to this I was getting in trouble with
Error in dyn.load(file, DLLpath = DLLpath, ...) :
unable to load shared library '/home/louis/R/i486-pc-linux-gnu-library/2.10/rjags/libs/rjags.so':
