I listened to the introductory part and the practical part. If you are new to R, I recommend that you listen to the basic part by teacher Lee Bu-il and then come to this course. After listening to the lecture, I understood it well. The statistics part is difficult in theory, so I will have to listen to it several times. The lecture style is not standardized, but the kindness part is top notch! The video style is not clean and continuous, and it feels like it breaks up a lot, so that part is very disappointing. Good luck!
