Google Developers R Programming Video Lectures

(This article was originally published at Getting Genetics Done, and syndicated at StatsBlogs.)

Google Developers recognized that most developers learn R in bits and pieces, which can leave significant knowledge gaps. To help fill these gaps, they created a series of introductory R programming videos. These videos provide a solid foundation for programming tools, data manipulation, and functions in the R language and software. The series of short videos is organized into four subsections: intro to R, loading data and more data formats, data processing and writing functions. Start watching the YouTube playlist here, or watch an individual lecture below:
