I have a web service that uses an R script to perform the analysis. At the end of the R script, I use the system function to call an external (perl) script that sends the user an e-mail telling them that their analysis has finished running, and where they can download the results. However, if the R script crashes (say...
Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : line 5 did not have 42 elements Calls: as.matrix -> read.table -> scan Execution halted ), I want the R script to call an external script that will e-mail the user telling them that an error has occurred. I do not want to use try-catch blocks because I want this to happen no matter what/where the error, and because the script is large and it would be unwieldy to try to catch specific things. Is this possible, and if so, how? Thank you very much in advance for any help! -- View this message in context: http://r.789695.n4.nabble.com/Perform-task-on-error-tp4672258.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.
