One thing that I do when I have a long script is to put "progress" report messages. These have some comments so I can chart the progress and also print out the current CPU and memory usage so I can also isolate where potential problems might be. This will help narrow down the section of code where the error occurred. Are you also running with options(error=utils::recover) so that when the error occurs, you get the stack and current environment so that debugging is easier?

Is it possible to get a line number with an error report?
I have a long script and an error:
Error in `[.xts`(x, xsubset) : subscript out of bounds
It would be very helpful, and save a lot of time, if there was some
indication in the error message which line the error was.
I can find it using binary search but that is a painful process.
