R2winBUGS & WinBUGS gui
I am trying to figure out if it is possible to run winBUGS from within
R, using R2winBUGS, without having winBUGS spawn any windows (basically
- 'true' batch - no GUI actions at all). The reason being I have a
machine which I (and several others) ssh/telnet into, and would like to
run winBUGS without having to mount a virtual desktop of any kind.
I've looked through the r2winBUGS

Can WinBUGS run two processes through R at the same time?
Dear all,
I want to run two winBugs process through R (by R2WinBUGS package).
The first WinBUGS process can successfully perform under R.
The error message appears while I put the code to run for the second
WinBUGS.
The error message:

Saving WinBugs log file when using bugs()
Hi,
I am very new to R and Winbugs. I have been provided with a code that runs
Winbugs from R. The code runs 60 different models and I would like to
either save the Winbugs log file for each of these or reproduce the WinBugs
plots which show convergence over the iterations.I can do this by using
Debug=true and saving manually each time but obviously this is very time
consuming.
Many thanks

Are they fully identical: WinBUGS and OpenBUGS; R2WinBUGS and R2OpenBUGS
Hello ALL!
I am running Linux, Fedora 15 64-bits, and R on it. I need to use
WinBUGS and R2WinBUGS, but as far as I read, WinBUGS is closed project,
to be continued with/as OpenBUGS. Thus, I have found R2OpenBUGS on
OpenBUGS Contributed Code (http://openbugs.info/w/UserContributedCode),
not on CRAN. Author(s) states that it is equivalent for R2WinBUGS. I
tried briefly, and realized few minor

How to connect R and WinBUGS/OpenBUGS/LinBUGS in Linux in Feb. 2009
Hi all,
I've managed to get JAGS working on my Ubuntu Hardy Linux with a 32-bit
computer and AMD processors using R 2.8.1. JAGS is great. I've read that
JAGS is the fastest, but that hasn't been my experience. At any rate, I
have more experience with WinBUGS under Windows and would like a version of
that working as well.
It seems like I've read a lot on the subject and tried a

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:

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:

beta1=1.5
beta2=-1
beta3=2

Using WinBUGS from R: A Multi-Way Array Problem
Please suggest a way out to the following problem.
I have a T by n data matrix (say Y) where coulmns are time series of length
T.
To do some analysis in WinBUGS I need to construct my data as follows.
yy<-rep(Y,k) ## this will be a vector
Yk<-array(yy,dim=c(T,n,k)) ## data array
Here the definition of dim indices is
first index: T rows
second index: n columns
third index: for kth T by n

question about calling winbugs in R
Dear All:
Do you have any experience on calling winbugs in R enviorment? I uploaded R2winbgus, pktools, BRugs, ect. in order to call winbugs. In the end, I try to use bugs(). The error message still displays that bugs() can not find.
Do you have any similar issue? If so, could you give your advice?
Many Thanks!

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).

WinBUGS breaks under WINE > 1.1.12
Dear Wine-friends,
I was wondering if any of you would have a clue around why WinBUGS (http://www.mrc-bsu.cam.ac.uk/bugs/), a nifty Markov chain Monte Carlo sampler widely used in Bayesian statistical modelling, no longer works when run through any version of WINE newer than 1.1.12.

WinBUGS posterior samples (via R2WinBUGS)?
Hi all,
I did some analysis using package R2WinBUGS to call WinBUGS. I set the
iterations to 50000 (fairly a large number, I think), but after the program
was done, the effective posterior samples contained only 7 draws. I don't
know why.
By the way, I checked posterior sample size by using bugsobj$n.sims. And,
for my previous practice with WinBUGS/R2WinBUGS, no such strange thing
happend.

a small question about R with Winbugs
I try to do a test for dirichlet process for Multivariate normal, but Winbugs
always says "expected multivariate node", does that mean I miss something at

R2WinBUGS and calling WinBUGS in Crossover/WINE
Hi there - I have a question for any of you who use R2WinBUGS to call
WinBUGS using the useWINE option in that package.
I have Codeweaver's Crossover emulator installed on my Intel Mac with
WinBUGS working fine if I start it from Crossover. But there is
supposed to be a way to start it directly from a command line, which I
could pass to the R2WinBUGS using the bugs(...,
