R SIG Debian - Jul 2011 - JAGS 3.0 and the Ubuntu repositories: A fix for jrags users

Ubuntu R users,

Early this month, version 3.0 of JAGS was released on its Sourceforge 
page.  Dirk Eddelbuettel and I quickly rolled up packages for Debian and 
Ubuntu, respectively.  If you are an Ubuntu user who utilizes my 
Launchpad PPA for your R related .deb files, JAGS was updated automatically.

The downside to this is that JAGS 3.0 is not compatible with the R 
package rjags, also found on my PPA.  rjags has not be updated to work 
with 3.0 yet.  So, if you are using JAGS 3.0, rjags will fail to load in R.

One solution is to roll JAGS back to version 2.2.  In order to make this 
easier, I have added JAGS to the CRAN Ubuntu repository, which will 
contain the last few versions of JAGS built for Ubuntu, including 2.2. 
Links on how to pin (apt) or force (Synaptic) the version of a package 
are given below.  Please note that it could take up to a day to sync to 
your CRAN mirror.

Please let me know if you have any questions,
Michael
