Training on Statistical Data Analysis using R

About the Course 

R is an open-source programming language that provides a wide variety of statistical and graphical techniques.  R has “become the de-facto standard for writing statistical software among statisticians. This course will give you a solid foundation in creating statistical analysis solutions using the R language, and how to carry out a range of commonly used analytical processes.

Target Participants 

This course is intended for Data Scientists, Data Analysts, Business Intelligence Analysts and any other professional who want to explore the vast range of analytical and graphical capabilities of R.
