We cannot help much more if you do not tell us what the > technical reasons are why mcapply() does not work. If the work you are doing within each iteration of the loop is trivial, you will likely even see a decrease in performance if you try to parallelize it. Without more info from you regarding your problem, there's little we can do to help, tho. -Steve -- Steve Lianoglou Graduate Student: Computational Systems Biology | Memorial Sloan-Kettering Cancer Center | Weill Medical College of Cornell University Contact Info: http://cbio.mskcc.org/~lianos/contact [[alternative HTML version deleted]] ______________________________________________ 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.
