Hello I'm trying to set-up a cluster having three nodes with cluster type=SOCK. I have a problem to give the path to the rscript (different on the two machines).... I try to give full information (fill the list(host, rscript) as in the makeCluster example)

I'm really thankfull if you can give me advice and tell me wether I do something wrong or not! Thanks a lot! See: library(snow) #local host only host212Full <-list(host = "dsge at 192.100.100.212", rscript = "/usr/lib64/R/bin/Rscript") makeCluster(c(rep(host212Full, 2)), type = "SOCK")
I think the immediate problem is the way that you're creating the first argument to makeCluster. Your code is concatenating host212Full to itself, creating a list of length 4 with elements that are not lists. I think you want to create a list of two lists, each of length 2. One way to create the appropriate list (which worked for me on R 2.8.1) is: makeCluster(rep(list(host212Full), 2), type = "SOCK") I hope that helps.
