Using R in the Enterprise

Course Overview

R has become the default data science and statistical modelling tool across all shapes and sizes of organisation. R is open source, and its functionality can be extended by community written packages, significantly increasing its power and flexibility. R can be used standalone, in a notebook environment like R Studio or Juptyer, or embedded in enterprise reporting tools such as Oracle’s OBIEE and Data Visualisation tools.


This course aims to teach people with a background in enterprise reporting, data visualisation, data, or business analysis the fundamentals of R and how to use it in an enterprise context. The lessons and labs use both local datasets and outputs, and Oracle's database and reporting tools to teach students how to perform simple data manipulation build models and visualise the results.
