Definitely a deep-dive worth taking, this course about R fundamentals highlights the use, benefits, features and much much more about the language - quite in depth. I lacked only the exercises to practice all this theory and although at times the lessons were slightly repetitive, overall it is worth it!

The course goes through the different areas of data science with python. Beside a fundamental theory regarding the explained concepts, the diverse concepts are exemplified with short python programs. The lessons are good to understand and the programs presented to illustrate and implement the concepts are simple and significant.
Amazing material put together, it really goes in depth with functions on Excel, R, and SAS. I really like the complexity and the level of knowledge specially the Excel area. If you are looking to analyze data on a regular basis using excel 2010, or similar platforms such as R, this training is full of great content at a very high level.
