Not an update but a heads up. I am temporarily suspending these incremental updates as I develop an entirely new version of R Instructor that will have to downloaded from the App Store. Two such updates will be coming soon. The first update will contain very minor visible changes but a number of large under-the-hood optimizations. The second update will expand and reorganize the content. 

If you have any suggestions or requests for content feel free to send me an email!

Best,

Shidan
