Why should you read RStudio for R Statistical Computing Cookbook?
Well, even if there are plenty of books and blog posts about R and RStudio out there, this cookbook can be an unbeatable friend through your journey from being an average R and RStudio user to becoming an advanced and effective R programmer.
I have collected more than 50 recipes here, covering the full spectrum of data analysis activities, from data acquisition and treatment to results reporting.
All of them come from my direct experience as an auditor and data analyst and from knowledge sharing with the really dynamic and always growing R community.
I took great care selecting and highlighting those packages and practices that have proven to be the best for a given particular task, sometimes choosing between different packages designed for the same purpose.
