R: Cross-Platform Compatible Language

Since R is a cross-platform compatible language, you can run the same R code in multiple operating systems. Let’s say, you are using a windows system, but your client has a MAC, you don’t have to worry at all, because your R code will run without any problems on your client’s system.

R: Visualization Tool

R is a great visualization tool. It provides multiple packages such as ggplot2, ggvis, and plotly with which we can create stunning visualizations. This is also one of the major reasons why people learn R Programming. When it comes to data visualization in R is far ahead when compared to Python.

R: Data Science and Machine Learning Tool

With the help of R language, you can implement various machine learning algorithms such as Linear Regression, Decision Tree and Naïve Bayes.
