similar to: Running MCMC using R2WinBUGS

Hi All: I had a basic question to ask. I am running R2WinBUGS so that I could automate the running of my model using 1000 simulated datasets. Below is the code I am using. The only problem I am having is the bugs output that comes out shows my parameters as nos with 1 decimal place after. I would want to have the parameters with 5 places after decimal. How would I specify that in my code for

Trevor, Thanks for your reply. That doesnot help Any other suggestions?

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 initialization? I will really appreciate the help to solve this problem Here is the R code, and Winbugs code. model { for(i in 1:N){ y[i,1:2] ~ dmnorm(mu[i,],tau[i,,]) S[i] ~ dcat(pi[]) mu[i,1:2] <- mu.star[S[i],]

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

Hi folks, I'm forwarding this to the list as my email to nita was about getting her code to the list. Additionally, I'm running Linux and have no experience with WinBUGS.

Dear all, I'm having a slight issue with R2WinBugs.... it cannot detect where WinBUGS is located. Q: How can I change the default path? Any advice is greatly appreciated. Thanks. Regards Erica I'm using R2WinBUGs (R version 2.21.1) on windows platform (Windows 7). I have downloaded WinBUGS14.exe and patch 1.4.3. As i'm working with Windows 7 (similiar issues to Vista occur),

Dear friends - I'm on winXP, R 2.71 - I have with some help dveloped this multivariate normal model, which gives very plausible results in WinBUGS even without any initial values specified. However, when I then try to run the same model via the bugs function in R2WinBUGS with inits specified as inits=NULL the program stops in a dead end. So I have tried to make inits for the bugs function

Dear R user: I am using R2WinBUGs to call WinBUGS from R. But I have some problems in using either the option bugs.seed and summary.only in the function bugs. Here are the programs and error messages. It appears that if I don't use either option, the program runs fine. I am using R2.5.1 and WinBUGs14. The program is not running: > schools.sim <- bugs(data, inits,

hi all i would like to use r and winbugs in order to undertake seemingly unrelated regression. i am using the R2WINBUGS library. i just simulated a simple example (sample size is 25) in order to get the correct code. i suspect that the problem is in my definition of the prior. it wants a multivariate node. the example could be extended by including more than 1 X variable in the system of

Hi! I am new to BUGS and running BUGS from R.

Hi All Does anyone know if I can avoid to use the write.model() function below? I dont want to do this. Can't bugs() do that automatically for me just by specifying the 4th argument 'model'? Just I like I am also using the 'inits' object! If I use 'model' in the same way as I use 'inits' I am getting the error: > sim <- bugs(data, inits, parameters,

Dear all, I tried to run WinBUGS model in R by using package R2WinBUGS, but I failed because of the massage : cannot calculate DIC for model in log file of WinBUGS14. In fact, the model works in WinBUGS and I can get summaries of the model, such as density, stats..., except DIC , because DIC may not be appropriate in this kind of model due to some reasons(according to the manual of WinBUGS14),

Dear UseRs, Apologies, I tried to post to the list yeasterday, but (for some reason) part of my message got missed off. Here's a second attempt. I am having some problems using R with WinBUGS using the R2WinBUGS package. Specifically, when I try to run bugs() I get the following message. Error in FUN(X[[1L]], ...) : .C(..): 'type' must be "real" for this format To

Hello, I'm using dmnorm from the package {mnormt} and getting strange results. First, according to the documentation, dmnorm should return a vector of densities, and I'm only getting one value returned (which is what I would expect). I've been interpreting this as the joint density of all values in the x vector (which is what I want). Should a vector of densities be returned, and if

Dear R help; I'm currently trying to combine a large number (about 30 x 30) of large .csvs together (each at least 10000 records). They are organized by plots, hence 30 X 30, with each group of csvs in a folder which corresponds to the plot. The unmerged csvs all have the same number of columns (5). The fifth column has a different name for each csv. The number of rows is different. The

Dear, I am running the following R code using the R2WINBUGS package. fit<-bugs( model.file=BUGScode, data=data, inits = list(geninits1,geninits2), parameters.to.save=keepers, n.chains=nchains, n.iter=runs, n.burnin=burn, n.thin=nthin, bugs.directory="C:/Program Files/WinBUGS14" ) I put this code and the corresponding WINBUGS code "BUGScode" in the same folder

Dear people, I'm trying to do some analysis of a data using the models by Royle & Donazio in their fantastic book, particular the following function: http://www.mbr-pwrc.usgs.gov/pubanalysis/roylebook/panel4pt1.fn that applied to my data and in the console is as follows: > `desman.y` <- structure(c(3L,4L,3L,2L,1L), .Names = c("1", "2", "3",

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
