Error with BRugs 0.53 and 0.71, on Win7 with R 2.12.2 and 2.13.0 (crashes R GUI)

Thanks again. FWIW, I tried an even older R version (2.11) + BRugs 0.53 and 0.70 ... but got the same errors as with the iterations reported below. So I'm giving up on trying to solve the issue. My workaround is that I'm using the R2WinBUGS package instead. So far that has worked well -- I've run a few iterations of models with no problems. Specifically, none of the errors below have occurred (this is using R 2.13.0, R2WinBUGS 2.1-18, OpenBUGS 3.0.3 as installed by BRugs, running under Windows 7/32-bit). Unlike with BRugs, I'm able to use R2WinBUGS to run a model, change it, run again with new parameters, etc., with no crashes or other problems yet.
Strange, since the BRugs example always worked well for me and some others. Hence I cannot tell where the interaction comes from that causes the crashes.
Uwe: thank you for your work there as well!
Well, I am very far behind my schedule for BRugs!!! Best wishes, uwe

Uwe -- thank you. No, this occurs on three different machines: two at work (a Lenovo laptop running Win7-32, plus an HP workstation running Win7-64) ... and I just tried another Compaq desktop machine at home running WinXP-32, with the same result. I agree that this seems highly unusual since the examples are so simple and obviously work in general; yet it is also highly replicable for me, and I'm at a loss as to what might be the root cause given the different machines and Windows versions. FWIW, everything else in my R environment (Rgui, Tinn-R, RStudio, ggplot2, various other packages) runs OK. OpenBUGS in itself also seems OK albeit in limited tests. Could there be something in the "handleRes()" error that suggests anything to examine (firewall, antivirus, file locations, or some file permissions, perhaps? -- although those also vary across my machines, esp. from work to home).
The only thing I can say is, yes, perhaps. Sorry, but I am still unable to reproduce so far. Uwe

Sounds like a hardware problem to me, since I do not expereice any problems with the example you gave at first. Is this all on the same hardware? Uwe Ligges On 27.05.2011 18:38, Chris Chapman wrote:
I've run into persistent problems with OpenBUGS crashing when using
BRugs .53 and .71, and am hoping someone has suggestions. There is
obviously something unusual going on in my environment, but I'm at a

In a nutshell, what happens is that, as soon as I call "modelCheck()"
in BRugs, it gets an error or crashes ... but only some of the time
(90%< p< 100%). Following are details:
1. OpenBUGS 3.0.3 + BRugs 0.531:
It works occasionally, but approximately 90% of the time, I get the
following error from modelCheck():
Error in handleRes(res[[3]]) :
An OpenBUGS module or procedure was called that did not exist.
The specific code seems not to matter, but here is an example (model
taken from the OpenBUGS tutorial):
modelString =
" model
{
for (i in 1:N) {
r[i] ~ dbin(p[i], n[i])
b[i] ~ dnorm(0, tau)
logit(p[i])<- alpha0 + alpha1 * x1[i] + alpha2 * x2[i]
+ alpha12 * x1[i] * x2[i] + b[i]
}
alpha0 ~ dnorm(0, 1.0E-6)
alpha1 ~ dnorm(0, 1.0E-6)
alpha2 ~ dnorm(0, 1.0E-6)
alpha12 ~ dnorm(0, 1.0E-6)
tau ~ dgamma(0.001, 0.001)
sigma<- 1 / sqrt(tau)
}
"
print(modelString)
writeLines(modelString,con="model3.txt")
modelCheck( "model3.txt" )
Which (usually) produces:
modelCheck( "model3.txt" )
Error in handleRes(res[[3]]) : An OpenBUGS module or procedure was called that did not exist. I've copied at the end of this message an example from a single R session that shows how it may work sometimes but not others. 2. OpenBUGS 3.2.1 + BRugs 0.71: As above, the model occasionally works, but mostly it crashes R on the modelCheck() line with the error "R for Windows GUI front-end has stopped working". I've tried the following combinations to try to get it to work: A. Win7 32-bit + R 2.13 + BRugs 0.531 from standard CRAN repository (installed from R) B. Win7 32-bit + R 2.13 + BRugs 0.71 + OpenBUGS 3.2.1 (package and EXE from OpenBUGS site) C. Win7 64-bit [different machine] + R 2.13 (32-bit) + BRugs 0.531 D. Win7 64-bit + R 2.13 (32-bit) + BRugs 0.71 + OpenBugs 3.2.1 E. Win7 32-bit + *R 2.12.2* + BRugs 0.531 from standard CRAN repository (installed from R) F. Win7 64-bit + R 2.12.2 (32-bit) + BRugs 0.531 G. Win7 64-bit + R 2.12.2 (32-bit) + BRugs 0.71 + OpenBugs 3.2.1 H. ... and various combinations of removing all R and openbugs versions, clean installs, and trying again In all cases, it occasionally works -- especially on first re-install of the package -- but then generally gives the "handleRes" error with BRugs 0.531 or crashes with BRugs 0.71.
