R as a programming language has taken the world by storm especially because of its capabilities in terms of data science and data visualization.

By virtue of being open source, R can be learnt without incurring any additional cost given the fact that there are myriad resources on R freely available over the internet.

Getting started is as simple as following the steps mentioned below:

  • Download the CRAN of R from R’s website
