This is the same reason I've also floated use of foreach in the past. But then you have the situation of multi-machines w/ multiple cores -- is this (2) or (3) here? How do you explicitly write code for that w/ foreach mojo? I guess the answer to that is that you let your "grid engine" (or whatever your SGE equivalent is that you might be running) handle that for you. -- 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 _______________________________________________ Bioc-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/bioc-devel
