Nathan Yau of Flowing Data talks about R Tutorials that he created for his site @R-bloggers.com:
“My main hope is that the tutorials provide a good starting point for people to visualize their own data in whatever way they like. So I have tutorials on specific visualization types, such as calendar heat maps or area charts, but I’ve also written generalized tutorials on creating custom charts and working with color. For the former, I try to wrap up all the code in a function so that it can be used right away. With the latter, I try to relate back to the more specific visualization tutorials so that you can see how the generalizations apply. In the end, whatever route you choose to learn visualization, it comes down to practice. Reading books on design concepts is good to start with, but you don’t get any better at visualization until you make stuff and apply what’s in the book. That’s where all the fun’s at.”
