R-Analytics

Before to continue with the posts about how to do things with R, I have decided to describe how I lead the creation of an analytics team starting from zero. My only intention here is for this information to be useful for companies looking to create their analytics team. Well, first the first, the people for your team. How many people is needed will depend on your company size or on the amount of money the company wants to invest in the analytics team creation but, at least you must have 2 developers, just ensure they are real developers. Now, it is needed to define the software to use. Database , for this I suggest to start small, let's say, using MariaDB, or SQLServer if you want to pay for a license, just ensure you can run analytic functions, some of them call them window functions, they are very useful when doing analytics.
