I'd highly suggest to start directly in OpenBUGS (without R):
An opened trap windows means you have generated some BUGS error. Hence
the problem is not on the R side ...
Once you got it to work, you can switch over to R and use WinBUGS more
remotely and embed the stuff in your other R functions.

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 both
begin to compute but do not end. If I use a simple model with data and
initial values bugs() works fine. So, I have to assume that there is
something in my model which is not compatible with bugs().
The model is:
-------------------------------------
model generateStartingValues
{ for (s in 1:Datasets) {
lambda[s]~dunif(0.1,0.9)
for (i in 1:K){ eltheta[s,i]~dunif(0.1,0.3)
q[s,i]~dunif(0.1,0.4) } }
}
-------------------------------------
DATA
list(K=19,Datasets=500)
As I said this works fine with openBUGS and WinBUGS.
I start BUGS from R-Console with
--------------------------------
Datasets <- 500
K <- 19
data <- list("Datasets","K")
mod1 <- bugs(data,inits=NULL
,model.file="generateStartingValues.bug"
,parameters=c("eltheta","q")
,n.chains=1, n.iter=1000
,bugs.directory="D:/WinBUGS14"
,debug=TRUE
#,program="openbugs"
)
--------------------------------
After starting bugs() the WinBUGS-Window has been opened (log- and
trap-window) and after a long while (10 minuites-trial and one
hour-trial) it does still compute or what ever. If I close the WinBUGs
window the R-Console gives:
****************************
Fehler in bugs.run(n.burnin, bugs.directory, WINE = WINE, useWINE =
useWINE, :
Look at the log file and
try again with 'debug=TRUE' to figure out what went wrong within Bugs.
****************************
There is no log-File but I copied the content of the log-window (see
below).
If I start openBUGS from R:
After about 5 seconds a window appears indicating a "dwwinn.exe-Error":
********************************************
dwwinn.exe - Fehler in Anwendung
Die Ausanahme "unknown softare exception" (x800000003) ist in der
Anwendung an der Stelle 0x7c91120 aufgetreten.
OK Cancel
********************************************
The output on R-Console is
***************************************
model is syntactically correct
data loaded
model compiled
initial value generated, model initialized
Sampling has been started ...
***************************************
To finish I have to close the R-console.
Maybe there is something I missed. I would be very happy if somebody
could give me a hint. I could use the stand alone versions but working
with R is so comfortable.
Thank you
Fabio
