Hi, I've noticed that the usual "break", "next" commands do not work in a foreach loop, is there a nice way to do that?
A little more detail: I am using foreach to conduct a very time consuming (may take several days if done sequentially) simulation study. The number of simulations is set to 1000. So the command I am using looks like this simplified version: grandsum <- foreach(icount(1000), .combine="+") %dopar% { sim(...) } In fact, grandsum can never take a value greater than a threshold, say 10.0. So I want the number of iterations depend on the value of grandsum. Say when the grandsum is greater equal to 10.0 the computation should be terminated to save time. This is the for loop version of what is in my mind: grandsum <- 0 for (i in 1:1000) { if (grandsum >= 10.0) break else grandsum <- grandsum + sim(...) } Is there a way to re-write the above for loop by an equivalent foreach/dopar loop? Thanks very much, Xing ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
