    Yes, if the error occurs in code that has line number information.
    You get line number info by default if you use source().  If the
    error is deeply buried in code that doesn't have the info (as it may
    be in your case), then the suggestions to use options(error=recover)
    will offer you a stack trace that shows you which high level code
    called the function reporting the problem.

        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.
