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
bugs function

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

R2WinBUGS: Data loading error
Hi R-Help!
I am trying to use R2WinBUGS but I get the following error message in WinBUGS

WinBUGS and it worked):

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])

error in using R2WinBUGS on Ubuntu 6.10 Linux
I am trying to run WinBUGS 1.4 from the Ubuntu 6.10 Linux distribution. I am using the R2WinBUGS packages with the source file listed below. WinBUGS appears to run properly, but I get the following message after WinBUGS starts in WINE. Does anyone know what may be causing this error and what the correction may be?
Thanks

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 and Compare DIC versus BIC or AIC
Dear All
1)
I'm fitting spatial CAR models
using R2Winbugs and although everything seems to go reasonably well (or I
think so)
the next message appears from WINBUGS 1.4 window:
gen.inits()
Command #Bugs: gen.inits cannot be executed (is greyed out)
The question is if this message means that something is wrong and the
results are consequently wrong, or Can I assume it as a simple warning

R and WinBUGS (via R2WinBUGS) error
Dear UseRs,
Apologies, I tried to post to the list yeasterday, but (for some
reason) part of my message got missed off. Here's a second attempt.
I am having some problems using R with WinBUGS using the R2WinBUGS
package. Specifically, when I try to run bugs() I get the following
message.

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.

Zero truncated Poisson distribution & R2WinBUGS
I am using a binomial mixture model to estimate abundance (N) and
detection probability (p) using simulated count data:
-Each site has a simulated abundance that follow a Poisson
distribution with lambda = 5
-There are 200 simulated sampled sites
-3 repeated counts at each site
- only 50 percent of the animals are counted during each count (i.e,
detection probability p =0.5, see codes)

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

how to update a bugs-model from inside R using R2WinBUGS
Hello there,
is there a way to update a model, which was called by "bugs()"? For
instance starting with few iterations and then updating more and more,
as is possible inside the WinBUGS-window. If set "debug=TRUE", then the
window remains open and updating is possible, but it is no longer
written into the R-object. Is it generally impossible?
Thanks,

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

R2WinBUGS under Linux/WINE fails

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:
> sim <- bugs(data, inits, parameters,
