Join Mark Niemann-Ross for an in-depth discussion in this video What you should know before watching this course, part of Code Clinic: R (2015).
- If you've never programmed a computer before you'll probably find this course baffling. Especially since R can be somewhat of a confusing language. If you've never programmed a computer, try Foundations of Programming with Simon Allardice. It's an excellent introduction to basic computing concepts and you'll be much happier when you return to this course. Likewise, a background in R is helpful. Try Up and Running with R with Barton Poulson. It isn't necessary, and if you've mastered another programming language, this code clinic will be very useful.
Before, during, or after viewing a solution in R, you might want to view some of the other code clinic courses. Comparing how a problem is solved in one language will give you insights into the other languages, including R.
Mark introduces challenges and then provides an overview of his solutions in R. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
