Protocol emailing R Package creators I have found an R Package written up that does exactly what is required but cannot figure out a bug that has presented itself. I have gone through the code and source code for the function and cannot figure out the problem. The authors' emails were included in the documentation. Is it inappropriate to email the creators to ask if the bug has occurred before or if I have any faults in my arguments?
Assuming that the documentation does not explicitly tell you not to email the maintainers about bugs, and assuming that there's not a forum, bug-tracker, etc. for the package, then I think it would be perfectly reasonable to contact one of them via the email address they provide in the documentation.

If they provide no other means of reporting bugs in the package, then I don't think they'd have any justification for taking offence at being contacted at an address they provide alongside the package.
