how a latent state matrix is updated using package R2WinBUGS
I'm trying to understand how a latent state matrix is updated by the MCMC
iterations in a WinBUGS model, using the package R2WinBUGS and an example
from Kery and Schaub's (2012) book, "Bayesian Population Analysis Using
WinBUGS". The example I'm using is 7.3.1. from a chapter on the
Cormack-Jolly-Seber model. Some excerpted code is included at the end of

R2jags update, jags.parallel
Anyone used jags.parallel in latest version of R2jags?
Ubuntu Oneiric, just ran updates in R to get latest R2jags package which
supposedly has added jags.parallel command to send chains to multiple
cores ... but when I submit, I get:
test <- jags.parallel(d, inits, param, model.file="rats.bug",
n.chains=3, n.iter=2000)

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

R crashes when communicating with JAGS
Dear all,
I have a question regarding using JAGS and R. My problem is that every
single time I want to call JAGS from R the latter crashes (i.e. it
turns pale and the Windows tells me "R has stopped working".
Strangely, if there is a mistake in my jags code, this will be
reported without a crash. Only when the code is right and the model
should start to run, R stops working. I already

Installing Jags on 64 Bit Fedora
I know this has been covered before but I have read all the posts on this

JAGS/BUGS on gene expression data
Has anybody had issues running MCMC (either BUGS or JAGS) on data sets of
this magnitude (ie 30k x 20-30). I've been trying to run a hierarchical
random effects model on expression data but R completely stalls out on jobs
run on 32bit R on our server (doesn't respond...then eventually crashes out
with an exception fault). Would using 64bit R help with JAGS? (As far as I
know there's

Including a text file (JAGS model) in an R package
Hello,
I can`t figure out how to include a text file for use in an example in the .Rd help files of an R package I am writing.
I want the examples section of one help file to look like this:
\examples{
# Load the JAGS model
mod <- jags.model("model.txt")
}
The function jags.model tries to read in the file model.txt. So far every time I run R CMD check, I get an error message:

dgamma in WinBUGS and JAGS (rjags)
Hello,
In WinBUGS 1.4 manual
(http://www.mrc-bsu.cam.ac.uk/bugs/winbugs/manual14.pdf), the gamma
density is presented as dgamma(r,mu) where r and mu are the shape and
rate parameters, respectively. In JAGS (rjags) manual version 1.0.2,
May 9, 2008 (http://www-fis.iarc.fr/~martyn/software/jags/jags_user_manual.pdf),
on page 26 the gamma density is presented as dgamma(mu,r) instead of
dgamma(r,mu).

bayesmix - What is or where can I find JAGS executable?
Hallo!
I want to use the package bayesmix. Trying the

R crashes when communicating with JAGS
There is a thread on this topic already:
http://finzi.psych.upenn.edu/Rhelp10/2010-August/250934.html
I'm rather mystified by a similar problem and wondering whether I've
overlooked something obvious. I'm running with latest versions of R and
all packages, and latest version of JAGS running under Windows 7.
Here's the problem. I have some source code. It's given below -

and use the function "jags" to fit my models.
The problem is that the following a windowx with the following message

Request for jags package to be added to CRAN Debian/Ubuntu archives
May I request that Dirk's package for jags be added to the CRAN
archives for Debian and Ubuntu?
Installing the rjags package for R requires specific versions of jags
to be present on the system. The current version of rjags requires
jags version 2.2.0 or later but the version on the Ubuntu archives at
Canonical (i.e. not the CRAN archives) is 2.1.0-2
I can always install Dirk's package

getting a vector of unown size
Hi all!
I have written some code in C for simulating the fate of population
using a dll loaded in R. During this simulation the population may go
extinct such that the length of its trajectory is unknown beforehand. I
wonder there is a way to define the size of the result in C and make it
known to R to get the vector appropriately.
I have defined the output size very much larger than

Jags problem
Hi, all:
I met "Non-conforming parameters for function %*%" problem, when I run the
Jags model in R.
My model is like this:

et[i,j]<-yt[i,j]-beta0+betax*xt[i,j]+betat*t[i,j]

jags error message
Could anyone give me some clues as to the best way to debug this error message? I think it is from the passing of variables back to R from the jags function which does Bayesian fitting. The curious part for me is that the error messages seem random, yet the input data are always the same. Any suggestions most welcome.
Thanks
