Thank you all for the astoundingly quick responses. I think that the bounding open/closed braces approach sounds like the easiest solution for the moment -- though I look forward to seeing this all automated in a future version of R :)
Incidentally, I have indeed encapsulated much of the code as functions which I call using source(); the problematic (lengthy) front-end is a decision tree which tailors a specific analysis to designated files. This mimics the switch/case structure which I'm more familiar with in c/c++. There's a limit to how much can be neatly moved to a separate file. Thank you again for your assistance. -- View this message in context: http://r.789695.n4.nabble.com/How-to-completely-stop-a-script-after-stop-tp3218808p3437025.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.
