I've run across this issue and I couldn't find a satisfactory solution to the problem. error() is effectively a long jump. Moreover, if your C++ function calls an R API function, e.g allocVector(), and the latter calls error() ... you already know what will happen. Same for interrupts. ______________________________________________ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
