Hi Kristian

Are you talking about an array job on Sun Grid Engine (SGE), or something else? If SGE, 
you can access the array index from within R using:

arrayIndex <- Sys.getenv("SGE_TASK_ID")

The R script uses one dataset which I want to analyse a defined set of say 100 sets of variables. Which variables to choose should be determined by the job array index number. But how can the job index number handed over to the R script? Would this concept work out at all?
