stack overflow has a lot of R knowledge, in questions already asked and in an active community. Try looking if your question has been asked there before, and if not, ask it. Many beginner questions are not about a particular language but about logic and math, maybe you can give a look at math.stackexchange also. For more simple questions, language models are very good (Chatgpt/bing, Bard)
