Step by Step Guide for Installation of R language for Data Science & Machine/Deep Learning
Introduction to R
R is a programming language and free software for graphics and statistical computing supported by R Foundation. Data Miners and Statisticians widely use R language for Data Analysis and for developing Statistical Software. As of July 2019, R is ranked as the 20th most popular programming language by TIOBE index. Also, data mining surveys, polls and studies have shown substantial increase in popularity of R. R was created by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand, but now it is developed by the R Development Core Team.
Implementation of a wide variety of graphical and statistical techniques including time-series analysis, classification & clustering is made possible and easy with the help of wide variety of R libraries. With the help of vast majority of functions and extensions, R has been made easily extensible for its users. In terms of packages, R community is noted for its active contributions. C and C++ is used by R to perform computationally intensive tasks. As compared to other statistical computing languages R has much stronger Object-Oriented facilities for programming.
With the help of various additional packages, R becomes quite good as static, dynamic and interactive graphics. It can also produce publication quality graphics. Like many other programming languages such as MATLAB (Matrix Laboratory), R also supports variety of matrix operations.
The major data structures supported in R are:
1) Vectors.
2) Matrices.
3) Arrays.
4) Data Frames (similar to Tables in Databases).
5) Lists.
Scalars cannot be represented in R as a scalar data type, rather it is represented as a vector with length one.
Although R has a command line interface, there are several Graphical User Interfaces (GUI’s). The most specialized Integrated Development Environment (IDE) for R language is R studio. A similar integrated development environment is R Tools for Visual Studio. Some generic IDE’s such as Eclipse also provide facility to work with various R packages.
As RStudio Incorporation has no formal connection to the R Foundation (an organization which is responsible for overseeing development of R environment for statistical computing) so we have to separately install R language and RStudio.
First, we will install R language in this tutorial, and then we will install R studio in the tutorial available at this link.
The following is the step by step guide to install R language.
