Dear all, I recently started having some problemd with the coda package. I have also deleted it and then installed the package again. The problem is that I cant access the codamenu. That is ; ********************************************************************************************************************************************* > library(coda) > codamenu() Error in

Dear R users: I am using the package coda (the last verison in CRAN) to analyse the output from a MCMC Bayesian analysis. And I get unconsitented results. I have export the chain using the read.table function and after I have transformed this data frame to an mcmc object using the mcmc function. I am interested in three variables, when I use the function effectiveSize I have these figures:

Dear R users: I am a newby to R, under Windows XP. Sorry if my question is too obvious, but I have not found any answer in the archives. I was using the R-Coda package with R version 2.4.1 and everything was going OK. After upgrading to R v.2.5.0, I receive the following error message when I'm trying to run codamenu(): "Error in coda.options(default = TRUE) : cannot change value of

I'm having difficulty running R2WinBugs on a setup that previously worked for me (Dell Laptop, Windows XP service pack 3, R 2.11.1, WinBugs 1.43) . When I issue the following command smds.sim <- bugs (data, inits, parameters, "SMDSbrandLoc2.bug", debug = T, n.thin = n.thin, n.chains = n.chains, n.burnin = n.burnin, n.iter = n.iter) I get the following error in R

Hi All, I am trying to figure out how to use R-Coda with the output from OpenBugs. I have installed and loaded the packages BRugs and R2WinBUGS. I have successfully run a simple Bayes model in WinBUGS using R2WinBUGS' "bugs" and have used "read.bugs" to build the coda object. I can successfully switch to OpenBugs and run the same model and get the basic summary

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 would like to compute ergodic mean using MCMC output from WinBUGS. I tried using CODA package, but it seems that it is not implemented yet. Could anyone help me to compute this? Attached to this email are my output and index files. Kind regards, Raquel -- Raquel Rangel de Meireles Guimar?es Doutoranda em Demografia raquel at cedeplar.ufmg.br

The document R-exts contains the following example of using mathematics in R documentation. \deqn{p(x) = {\lambda^x\ \frac{e^{-\lambda}}{x!}} {p(x) = lambda^x exp(-lambda)/x!} There is a syntax error in there, but that's not my point. The problem is that using "R CMD Rd2dvi" I find that putting the alternate forms of the equation on top of each other doesn't work.

Appologies for cross-posting Dear R users, I am using R2WinBUGS to call WinBUGS from R. After loading data, model, and initial values I call this command res <- bugs(data = dfile, inits = list(ifile), parameters.to.save = c("beta"), model.file = mfile, working.directory = tdir, n.thin = nthin, n.chains = 1, n.iter = niterations*nthin, n.burnin = 0, DIC = F, debug = T,

I'm trying to read CODA/mcmc files (see the coda package), as generated by jags/WinBUGS/OpenBUGS, into a big.matrix. I can't load the whole mcmc object produced by read.coda() into memory since I'm using a laptop for this analysis (currently I'm unfunded). Right now I'm doing it by creating the filebacked.big.matrix, reading a chunk of data at a time from the chain

I'm trying to call BUGS from R. But it's not working. R freezes up and BUGS gives me a strange output in the log. Just to know, BUGS is registered. The modified date on the keys file is today (Dec. 9th). It should be fully registered so that I can use it fully. And, the BUGS model is syntactically correct. Any suggestions would be very helpful. Here is my BUGS model: model {

Hi, I'm running wine-1.0.1, OpenBUGS 3.0.3, R 2.9.0, and R2WinBUGS on a Redhat Enterprise Linux machine. Following various peoples' suggestions... This works perfectly (yay!): wine Z:/opt/OpenBUGS/winbugs.exe Within R, however, I get this: (setup the example from ?bugs, then....) R> schools.sim <- bugs(data, inits, parameters, model.file, n.chains=3,

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

I have successfully installed coda in R, and I am also able to read output from a Bugs run into coda.

Hello everyone, I need some help regarding calling WinBUGS from R. I have a model for WinBUGS and an R code which calls WinBUGS. On running the code I am being shown the error message : Error in file(con, "wb") : cannot open the connection In addition: Warning messages: 1: In file.create(to[okay]) : cannot create file 'c:/Program

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.

Dear all, I'm not 100% sure if this question is best directed at the r-list, or a mailing list concerned with Bayesian analysis, so please accept my apologies if another audience may be more appropriate. I have been using the rjags package to run Jags models with multiple chains and store the results in a Coda based mcmc list. For instance, having created a jags model and done initial

Dear all, I just wrote a script to have each of my three mcmc chins running on a different computer core to improve computation speed. To do it I use the function sfLapply from the package snowfall. Before using parallell computation, I did my diagnostic analyses just after the model updating, but now I have to save the coda before. Using the CODA package, it is possible to load the outputs in a
