[R] Hanging -- please help decipher event report
I'm running some code in R64 on a Mac OS 10.6.8 that calls a C program through the dyn.load() function. The code hangs after several days of computation, and I've having trouble locating the problem. Can anyone decipher this info from the error report, and tell me if this is a problem in R64, or in the C code? Thanks very much in advance. A few hints: "pa" is the name of the C function in R, and "polio_3A.so" is the compiled code. I can post the R code or the C code if anyone needs to see it, but my first priority is to figure out what this stack trace is telling me.

Re: [R] Hanging -- please help decipher event report
Thanks for your reply. At line 144 I call R_CheckUserInterrupt(). I added this because otherwise, R would not respond to the user for thing like switching over to the window until the C code exited back to R. I then moved that command into a loop where it should occur quite frequently, because I thought this would fix my hanging problem. I admit that I may be using this command in an inefficient or flat-out wrong way, as this is my first foray into R/C cooperation. I should add that I cannot get the C code to hang or produce any errors when I run it on its own. I would appreciate any additional thoughts or questions. -- View this message in context: http://r.789695.n4.nabble.com/Hanging-please-help-decipher-event-report-tp4355128p4355709.html Sent from the R help mailing list archive at Nabble.com. __ 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.
