Comprehensive Learning Path in R

I have built a comprehensive learning path for professionals, students and researchers at http://www.analyticsvidhya.com/learning-paths-data-science-business-analytics-business-intelligence-big-data/learning-path-r-data-science/

Rather than simply put a list of resources, I have tried to create a structured path which is agnostic to any one source instead takes in best sources for each step or phase in the analytics work flow.

There are links to resources by Hadley Wickham, Revolution , Data Camp, videos, live projects, slideshares, tutorials done in a systematic manner.

Have a look and let me know how this can be made better
