DataScience+
From the webpage:
We share R tutorials from scientists at academic and scientific institutions with a goal to give everyone in the world access to a free knowledge. Our tutorials cover different topics including statistics, data manipulation and visualization!
I encountered DataScience+ while running down David Kun’s RDBL post.
As of today, there are 120 tutorials with 451,129 reads.
That’s impressive! Whether you are looking for tutorials or you are looking to post your R tutorial where it will be appreciated.
Enjoy!
