error message running R2WinBUGS
*Dear R-user,
*
I try to run Winbugs from R using bugs function in R2WinBUGS.My model works
well in Winbugs except that I can't get DIC. Since I don't need DIC, when I
try to run Winbugs from R , I set "DIC=FALSE". My model is as following:
model {
for (i in 1:N) {
for(j in 1 : T ) {
x[i, j] ~ dbin(p[i, j],n[i])
#Hier.prior
p[i, j] ~ dbeta(alpha[i, j], beta[i, j])
alpha[i, j]

R2WinBugs problem
I'm having difficulty running R2WinBugs on a setup that previously
worked for me (Dell Laptop, Windows XP service pack 3, R 2.11.1, WinBugs
1.43) . When I issue the following command
smds.sim <- bugs (data, inits, parameters, "SMDSbrandLoc2.bug",
debug = T,
n.thin = n.thin,
n.chains = n.chains,
n.burnin = n.burnin,
n.iter = n.iter)
I get the following error in R

R2WinBUGS awkward to use
Hi All
Does anyone know if I can avoid to use the write.model() function below? I dont
want to do this. Can't bugs() do that automatically for me just by specifying
the 4th argument 'model'? Just I like I am also using the 'inits' object!
If I use 'model' in the same way as I use 'inits' I am getting the error:

The error while using R2WinBUGS
Dear all,
I tried to run WinBUGS model in R by using package R2WinBUGS, but I
failed because of the massage : cannot calculate DIC for model in log
file of WinBUGS14. In fact, the model works in WinBUGS and I can get
summaries of the model, such as density, stats..., except DIC , because
DIC may not be appropriate in this kind of model due to some
reasons(according to the manual of WinBUGS14),

Question regarding finding credible interval using r2winbugs
Dear

WinBUGS with R
Dear Users,
I am new to both of things, so do not blame me too much...
I am busy with semiparametric regression and use WinBUGS to sample
posteriors.
The code to call Winbugs is as follows:

inits.beta <- rep(0,K)
inits.beta0 <- 0

BRugs dwwinn.exe error
Hi,
I have a strange behaviour of openBUGS and WinBUGS when I start them
from R.
Version:
R: 2.10.1
openBUGS: 3.07
WinBUGS: 1.43
R2WinBUGS: 2.1-16
BRugs: 0.5-3
I have a model and data without initial start values. If I use the stand
alone versions of openBUGS and WinBUGS I don't have any problems and I
get what I want.
If I use function bugs() from R2WinBUGS- resp. BRugs-Library then

Making R talk to Win/OpenBUGS in Linux (again)
I'm back!
I've just learned that, on a fully updated Fedora Core Linux5 sytem,
the working solution to access Winbugs under wine via the R package
"rbugs" no longer works. Here was my last post on this topic (with
the formerly working solution) from January.

Errors when saving output from WinBUGS to R
Dear all
I used R2WinBUGS package's bugs() function to generate MCMC results. Then I
tried to save the simulation draws in R, using read.bugs() function. Here is
a simple test:

How do you calculate DIC from coda files (R2WinBUGS)?
I tried calculating pD as 1/2 variance of the deviance, but I got hugely
inflated numbers.
Does anybody know how to calculate pD from the coda files output from
R2WinBUGS?
By the way, 'set DIC' is greyed out for some reason within WinBUGS, so I
can't monitor DIC.

R2WinBUGS users,
I'm getting the error message "monitor could not be set" when I try to

R2WinBUGS sending variables as factors
Hello R and BUGS users,
I am writing a heirarchical model in R to send to BUGS via R2WinBUGS and
I am finding it difficult to get the model to run. I seem to be having
two problems.
1) I can't seem to send variables classed as factors (Month), is there a
way do this?
2) Checking the Log in WinBUGS I can see that the model is Syntactically
correct, but Bugs is not able to recognise the the

R2WinBUGS problem
Dear friends - I'm on winXP, R 2.71 - I have with some help dveloped
this multivariate normal model, which gives very plausible results in
WinBUGS even without any
initial values specified. However, when I then try to run the same model
via the bugs function in R2WinBUGS with inits specified as inits=NULL
the program stops in a dead end. So I have tried to make inits for the
