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

WinBUGS - R2WinBUGS problem
Appologies for cross-posting
Dear R users,
I am using R2WinBUGS to call WinBUGS from R. After loading data, model, and initial values I call this command
res <- bugs(data = dfile, inits = list(ifile), parameters.to.save = c("beta"), model.file = mfile, working.directory = tdir, n.thin = nthin, n.chains = 1, n.iter = niterations*nthin, n.burnin = 0, DIC = F, debug = T,

bugs() ignores my inits
Hi All
I can specify whatever inits, it has no effect on the estimation. I am
replicating a textbook example. The result is completely trash, having estimates
of -58.7 (sd=59.3), where it should be closer to an ml estimate of 0.585 (SE=0.063).
The two chains within one run are different, but with different inits for
different runs, I get exactly the same chains, and I mean exactly.
If I set

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])

R2WinBUGS under Linux/WINE fails
Hi,
I'm running wine-1.0.1, OpenBUGS 3.0.3, R 2.9.0, and R2WinBUGS on a Redhat
Enterprise Linux machine.
Following various peoples' suggestions...
This works perfectly (yay!): wine Z:/opt/OpenBUGS/winbugs.exe
Within R, however, I get this:

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.

WinBUGS14 and R
I'm trying to call BUGS from R. But it's not working. R freezes up and
BUGS gives me a strange output in the log. Just to know, BUGS is
registered. The modified date on the keys file is today (Dec. 9th). It
should be fully registered so that I can use it fully. And, the BUGS model
is syntactically correct. Any suggestions would be very helpful.
Here is my BUGS model:

Problems with R2WinBUGS
Hello,
I am trying to use R2WinBUGS to conduct a mixed treatment comparison (MTC)
analysis. On the surface, it seems to me that I am following the correct
steps: (1) reading the data into R, (2) specifying initial values for the
parameters in the model and (3) fitting the model to the data using the
bugs() function in R2WinBUGS. However, I get the error message

bugs.seed= and summary.only= option in R2WinBUGS
Dear R user:
I am using R2WinBUGs to call WinBUGS from R. But I have some problems in
using either the option bugs.seed and summary.only in the function bugs.
Here are the programs and error messages. It appears that if I don't use
either option, the program runs fine. I am using R2.5.1 and WinBUGs14.
The program is not running:

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:

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

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
