@@vittal255 R is fantastic for statistics and exploratory analysis, so it's still good to know. However, if I had to pick one then I'd say you can skip R and stick with Python, especially if you're new to coding or you want something more flexible. In terms of course material for computer vision, I don't really have anything to recommend. I usually go to Machine Learning Mastery and follow their guides, so maybe you could start there with their YOLO stuff.
