Taveras John L. R for Excel Users. An Introduction to R for Excel Analysts

Leanpub, 2014. — 21 p.This book is for beginners, and the goal is to get you started. R is known to have a steep learning curve: (1) data management, (2) statistics and (3) visualization.

Once you are able to work with data sets, performing statistical analysis, for the most part, will be a matter of applying functions to the data. The same applies to graphics.Getting Set Up
