Learning R takes practice. It’s like learning a musical instrument. There are many resources available on the internet to help with the process – some good, some not so good. Here at Lehigh, LTS offers a seminar/workshop on programming in R each semester. It’s a perfect, instructor led, introduction to R that focuses on some history and background, as well as a modern approach to programming.
