similar to: Error message R2Jags

Anyone used jags.parallel in latest version of R2jags? Ubuntu Oneiric, just ran updates in R to get latest R2jags package which supposedly has added jags.parallel command to send chains to multiple cores ... but when I submit, I get: test <- jags.parallel(d, inits, param, model.file="rats.bug", n.chains=3, n.iter=2000) Error: could not find function

Dear R users, I am having problems in trying to run R2jags on a Linux Cluster. When I tried to run the model given in the R2jags manual I get the following error error message: Error in FUN(X[[3L]], ...) : object 'J' not found Can any one help me with this problem? Looking to hear from you all. Regards, -- Luwis Diya, Leuven Biostatistics and Statistical Bioinformatics Centre

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.

Hi, I'm trying to install rjags and R2jags with R version 2.14.1 (2011-12-22) on Linux Mint 12 machine using software repository: deb http://cran.fhcrc.org/bin/linux/ubuntu oneiric/ jags seems to install OK, but rjags gives a weird error about not finding fprec symbol. Here is a history of the problem including several attempts to work around it. (Because of Ben Bolker's recent

I am using the loglin function of the base package to fit log-linear models. I am interested in obtaining the parameter values and their standard errors. Parameters are easily obtained, but I haven't found the way of obtaining their standad errors. Is this possible with the loglin function? If not, is there any other function to get them? Many thanks, -- Vicente Piorno Departamento de Ecolox?a

There is a thread on this topic already: http://finzi.psych.upenn.edu/Rhelp10/2010-August/250934.html I'm rather mystified by a similar problem and wondering whether I've overlooked something obvious. I'm running with latest versions of R and all packages, and latest version of JAGS running under Windows 7. Here's the problem. I have some source code. It's given below -

Hi All, I have a user who is receiving this error after running the following: library(rjags) library(R2jags) x = c(1.6907, 1.7242, 1.7552, 1.7842, 1.8113, 1.8369, 1.8610, 1.8839) n = c(59, 60, 62, 56, 63, 59, 62, 60) r = c(6, 13, 18, 28, 52, 53, 61, 60) N = 8 data=list("x","n","r","N") inits=function(){ list(alpha.star=0,beta=0) }

Try this: fn <- "tmp.dat" x <- 1:3 dump("x",file=fn) file.info(fn) ## 9 bytes file.copy(paste("./",fn,sep=""),fn,overwrite=TRUE) file.info(fn) ## 0 bytes (!!) Normally file.copy() checks and disallows overwriting a file with itself, but it only checks whether character string 'from' is the same as character string 'to'

So, I'm submitting R 3.0.1 jobs on Ubuntu (13.04) using 'R CMD BATCH --no-save filename.R &' (have an alias set to subr='R CMD BATCH --no-save") and am having a problem of sometimes the process ending without the R commands contained in the batch file actually having finished running. We're running Bayesian models using R2jags jags.parallel and it ends during the

Frank (or anyone else), can you offer any comments comparing runjags, R2jags, rjags ? I couldn't find any vignettes, nothing except a brief mention on Task Views.

I am generating 1000 replicate data sets in R, each data set is then analyzed with WinBUGS in batch mode using R2WinBUGS. Unfortunately, occasionally some data sets lead WinBUGS to open a "trap" window; and the simulations are interrupted as result of the message. Is there any ways to set R2WinBUGS so that it would ignore the trap message and proceed with the simulations? Cheers

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, Frederic

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

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

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: Error in file(file, ifelse(append, "a", "w")) : cannot open the connection In addition: Warning message: In file(file, ifelse(append,

May I request that Dirk's package for jags be added to the CRAN archives for Debian and Ubuntu? Installing the rjags package for R requires specific versions of jags to be present on the system. The current version of rjags requires jags version 2.2.0 or later but the version on the Ubuntu archives at Canonical (i.e. not the CRAN archives) is 2.1.0-2 I can always install Dirk's package

R2WinBUGS users, I'm getting the error message "monitor could not be set" when I try to monitor (and output to R) a response variable that includes missing data (NAs)...ie.e imputing for y. Setting monitors for other parameters works OK and running the R-generated WinBUGS script file in WinBUGS, also works OK. Below is my R code and the log.txt file output by R2WinBUGS. As I want to

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
