These posts are written by chatGPT based on a prompt where I have given it some code and asked it to explain a certain part of the code. Hopefully this will help me remember how to do stuff. While the other posts about R found here are written by me, this is only a library of code I have used and maybe want to reuse sometime. (Of course it may be useful for other people as well, but that’s not the main goal.) The double dot is used to denote sentences written by an LLM as proposed by Magnus Nome here.
