Asking for help with errors in statistical programming

No matter how experienced you are in statistical programming, you are certain to encounter errors in your code from time to time. You will recognize some of them and be able to solve them quickly, but you will never stop encountering unexpected new errors that you need help to resolve. Asking for help with statistical programming is hard. You need to give enough information to the person helping you so that they can produce the exact same problem you have
