My submission is my lecture notes for an introductory stats class to R programming. Here is a link to the book and a link to the repository containing all source documents. There are other books on the web page for the course (which is__http://www.math.utah.edu/~cmiller/classes/FA183070/ sorry but I'm not allowed to post more than two links since I'm a new user) for those interested (the source for all the books are in the same repository).
I can't say there's anything particularly innovative about my submission; the fact that it is a bookdown document seems innovative from the context I'm coming from. I wrote these notes using just markdown before, but I think that the bookdown format could help students better access the material.
Feel free to use and share my notes. Thanks for allowing me to submit!
