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

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)

dgamma in jags within r
I define priors in jags within r using a gamma distribution. I would
like to control the shape but I have problems. Any help will be usefull.

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:
model{
for(i in 1:n){
for(j in 1:t[i]){
et[i,j]<-yt[i,j]-beta0+betax*xt[i,j]+betat*t[i,j]
}
for(a in 1:t[i]){
for(b in 1:t[i]){
sigma[i,a,b]<-pow(rho0,abs(t[a]-t[b]))
}
}
phi[i]<-

problem with plots with short example.
i am having problem running my own data. yesterday it was working just fine. today it is not. this is the code i was using as an example to follow. this code ALSO worked just fine yesterday, and is no longer working at all. i suspect it is a problem with either my computer or the software, at this point. if THIS won't even run.... something is wrong.
i can assure you this isn't

bayesmix - What is or where can I find JAGS executable?
Hallo!
I want to use the package bayesmix. Trying the
examples I had no success. The reason is, I think:
> haveJAGS()
[1] FALSE
Have read of JAGS executable (I could not find
JAGS.exe in my R directory). What is JAGS? Where can I
find or download it?

cacheSweave fails when used in conjunction with rjags
Hi all,
I use the excellent packages rjags and cacheSweave, and unfortunately
seem to have found an incompatibility between them. Below are a
minimal .Rnw file and corresponding JAGS model file which illustrate
the problem:
*** JAGS model file; name=j.bug ***
model {
mu ~ dnorm(0,1.0E-5)
sigma ~ dunif(0,100)
for(i in 1:length(y)) {
y[i] ~ dnorm(mu,sigma)
}
}

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

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

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 -

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).

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

Error message R2Jags
Hi,
I'm trying to generate a GLMM for Y following a negative binomial
distribution. The first step I'm taking as a beginner in the use of R2Jags
is to generate a GLM for Y following a Poisson distribution (I heard it's
good in order to get used to the coding language), so here I am and here I
face the first error message for which I can't find any mistake of spelling.

R2winbugs : vectorization
I'm new to bugs, so please bear with me. Can someone tell me if the
following two models are doing the same thing? The reason I ask is
that with the same data, the first (based on 4 separate coeffs
a1--a4) takes about 50 secs, while the second (based on a vectorized
form, a[]) takes about 300. The means are about the same, though
R-hat's in the second version are quite a bit better.

Which JAGS interface to use?
Frank (or anyone else), can you offer any comments comparing runjags,
R2jags, rjags ?
I couldn't find any vignettes, nothing except a brief mention on Task Views.

RJAGS Installation Issues

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

Error in JAGS, cannot monitor z
Hello.
I am running a state space model (the example from Marc kery's Bayesian
population analysis using WinBUGS )
The code runs fine for the examle as shown in the book.
However I played around and changed the nodes monitored to the latent
variable z I get the following error- even though it is monitored in the
code:
