Dear R Users, what is the best way to trace the origin of warning messages? If an error occurs I can use traceback() to see where it comes from. I would like to do similar investigation, where a warning message originates from. Is there an option to turn warnings to errors? I tried the followingfWarn<- function(){ warning("A") } options(warning.expression = stop()) fWarn() traceback()2: stop() 1: options(warning.expression = stop()) Hence, it does not give me the desired stack trace and the information that the warning occured in function fWarn, so far. (using Windows XP, R version 2.10.1) Best regards Thomas Wutzler ______________________________________________ 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.
