Dear R users, I was wondering if anyone knows how to obtain(subset) the first and/or the last record of a subject in a longitudinal setup. Normally in SAS one uses first.variable1 and last.variable1. So my question is that is there an R way of doing this. Regards, -- Luwis Diya, Phd student (Biostatistics), Biostatistical Center, School Of Public Health, Catholic University of Leuven, U.Z. St

Dear R Users, I have a question, how does one print an r function like t.test in R (to get the whole function and not just a summary of the environment)? For example if I type the following: > t.test function (x, ...) UseMethod("t.test") <environment: namespace:stats> > print(t.test) function (x, ...) UseMethod("t.test") <environment: namespace:stats> I

Dear R users, I would like to fit cross classified or multiple membership logistic models or a 3 level hierarchical logistic model using the Umacs package. Can anyone advise me on how to proceed or better point me to examples of how its done.

I have been trying to write my own user defined function in Rpart.I imitated the anova splitting rule which is given as an example.In the work I am doing ,I am calculating the concentration index(ci) ,which is in between -1 and +1.So my deviance is given by abs(ci)*(1-abs(ci)).Now when I run rpart incorporating this user defined function i get the following error message: Error in

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.

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?

Greetings - I run a multi-pro server box (GNU/Linux), on which I've installed winBUGS under wine. Works fine, and plays nice with r2WinBUGS, provided everything is done through a graphical front-end (either by working from console, or using a virtual desktop via VNC or equivalent). However, I'm wondering if there is a way to use R2winBUGS and winBUGS such that winBUGS does not spawn

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

I have an array from an mcmc simulation and I'd like to try and use the monitor function in R2WinBUGS. The R2WinBUGS package is in the search path and when I try help(monitor) the help page appears for the function. But, when I try and use it the following happens: > monitor(sims) Error: couldn't find function "monitor" I've searched the archives but have not seen any

This weekend I noticed that my R2WinBUGS connection was no longer working on my Windows computer at work AND my Ubuntu linux computer at home. As soon as WinBUGS opens, the message reads Index Out Of Range. I have un-installed and re-installed R on both computers and the problem remains the same. At first I thought it was the new version of R, but I was able to overcome the problem (on Windows

Hi! I am new to BUGS and running BUGS from R. I am trying to run a regression model from R, however I have this 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 Files/WinBUGS14//System/Rsrc/Registry_Rsave.odc', reason 'Permission denied' 2: In file(con,

Hi R Users, I have--what I think--is a very basic question. I'm trying to use R2WinBUGS and am having difficulty setting up the data properly for repeated measures data in a hierarchical model. First, I know that it is me...not the package, as I sucessfully used R2WinBUGS to run a basic regression. Second, I know that it's not my hierarchical model as I've run it successfully in

For some purpose, I need to transfer a NAs array to WinBugs through R2WinBugs, But I constantly got an error message:"'type' must be "real" for this format". Here is my data to transfer: x = matrix(data=NA,nrow=3,ncol=3) x = as.array(x) data <- list ("x") if I add a line to above setting, then I can pass R2WinBugs: x[1,1] = 0 If I manually input the

Hi all, I did some analysis using package R2WinBUGS to call WinBUGS. I set the iterations to 50000 (fairly a large number, I think), but after the program was done, the effective posterior samples contained only 7 draws. I don't know why. By the way, I checked posterior sample size by using bugsobj$n.sims. And, for my previous practice with WinBUGS/R2WinBUGS, no such strange thing happend.

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

Hi there - I have a question for any of you who use R2WinBUGS to call WinBUGS using the useWINE option in that package. I have Codeweaver's Crossover emulator installed on my Intel Mac with WinBUGS working fine if I start it from Crossover. But there is supposed to be a way to start it directly from a command line, which I could pass to the R2WinBUGS using the bugs(...,

Hi all, I am having problems using the R2Winbugs function When I perform an analysis directly in Winbugs I can specify that the first 'n' iterations are to be done using an 'adaptive' phase. After this phase the markov chain seems to mix a lot better. I don't seem to be able to specify R2winbugs to carry out this adaptive phase, I can just specify the burnin length but

I am trying to figure out if it is possible to run winBUGS from within R, using R2winBUGS, without having winBUGS spawn any windows (basically - 'true' batch - no GUI actions at all). The reason being I have a machine which I (and several others) ssh/telnet into, and would like to run winBUGS without having to mount a virtual desktop of any kind. I've looked through the r2winBUGS
