There's no explicit link between foreach and Condor right now (although foreach is designed to work with any backend, so someone could write one if they wanted). If you use the NetworkSpaces back end (registerDoNWS in REvolutionR Enterprise), and can access members of the Condor cluster directly, you could always just set up a sleigh manually -- instructions are in the ParallelR manual. I expect you can do the same with snow (via the doSNOW package for foreach). Hope this helps, # David Smith
