1.7 Getting help
Currently, there are three main venues to get help when you’re stuck and can’t figure out what’s causing the problem: RStudio Community, StackOverflow and the R-help mailing list. You can get fantastic help in each venue, but they do have their own cultures and expectations. It’s usually a good idea to spend a little time lurking, learning about community expectations, before you put up your first post.
Some good general advice:
Make sure you have the latest version of R and of the package (or packages) you are having problems with. It may be that your problem is the result of a recently fixed bug.
Spend some time creating a reproducible example, or reprex. This will help others help you, and often leads to a solution without asking others, because in the course of making the problem reproducible you often figure out the root cause. I highly recommend learning and using the reprex package.
