If you are new to R, this course will get you started quickly and you will soon have great looking charts of your data. There's a lot of things you can do with R and for a newcomer, it might seem overwhelming. But if you are good with Excel, and many are, I think R is a suitable next level up in your statistical software tool kit. R is the universal language for serious statistical practitioners. It is a domain-specific language whose structure is fundamentally centered on data manipulation, statistical modeling, and graphical display. All of my work in the other courses on problem solving use R and so it makes it easier for you to run similar analyses with your data if you get over this initial learning curve.
