Hello, I have a memory problem when I run package WinBUGS with R (2.6.1). Until now I have been using a Pentium IV 3.2Ghz computer with 512Mb of RAM memory (with Windows XP Pro SP2), and I hadn't had any problem. Now I have a new computer with the following characteristics: Intel Core 2 duo 2.33Ghz and 3Gb of RAM memory (with Windows XP Pro SP2) and when I am running the same R syntax I receive the following error message: "Error: cannot allocate vector of size 216.0 Mb". This is an extract of my R syntax:> memory.limit(4000)NULL> simu.BYM<-bugs(data, inits, parameters, model.file="Modelo.txt", n.chains=3, n.iter=200000, n.burnin=20000, n.thin=180, debug=FALSE, DIC=FALSE, digits=5, codaPkg=FALSE, bugs.directory="c:/Archivos de programa/WinBUGS14", working.directory=NULL)Error: cannot allocate vector of size 216.0 Mb I have tried: -Change size of virtual memory inside Windows XP -change the R memory settings -run from DOS (R CMD BATCH...) -reviewed the R Windows FAQ and R-Help. but I haven't be able to find a solution ! Thank you very Much, Rodrigo

I recently fixed a minor bug that could have symptoms like this. Under certain conditions it would miscalculate the amount of available memory.
