dear R experts---I am looking at a fairly uninformative error in my program:
Error in mclapply(1:nrow(opts), solveme) : (converted from warning) all scheduled cores encountered errors in user code the doc on ?mclapply tells me that In addition, each process is running the job inside try(..., silent=TRUE) so if error occur they will be stored as try-error objects in the list. I looked up "try", but this manpage creates as many new riddles as it solves. so, it isn't obvious to me how I get to the try-error object list, or how to find out what triggered the abort. of course, I can use lapply to debug this, but this could be slow for some programs. (I know the answer for my problem is that a uniroot deep inside my code complained that my endpoints were not opposite.) in general, is there a way to get some more information from mclapply failures? could this be added to the docs for mclapply? /iaw ---- Ivo Welch (ivo.we...@gmail.com) http://www.ivo-welch.info/ ______________________________________________ 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.
