Overview

In this world of information overload and data explosion, there is a dire need to leverage this data and make sense of it all. R is rapidly becoming the leading programming language for effective data analysis and statistics. It is the tool of choice for many data science professionals in every industry. Star R Programming is an all-inclusive training program that aims at building a skill-set to tackle real-world data analysis challenges as a data engineer. It is a guide to understand how to program in R and how to use R for effective data analysis.

The program delves into intricacies of calculations, co-relations, and statistical probabilities and teaches the learners the fundamental understanding of programming with R, detailing all aspects of the language such as understanding and process data structures, and mining information through data analysis that can suit a wide variety of purposes, and sectors as varied as finance, defense, health, education, etc. Further, the program dives deeper into the graphical capabilities of R, and helps you create your own stunning data visualizations.
