8.1 PREREQUISITES
Before starting to learn machine learning programming in R, we need to acknowledge certain
prerequisites. Quite understandably, the rst and foremost activity is to install R and get started
with the basic programming interface of R, i.e., R console. Later on, familiarizing the R com-
mands and scripting in R is an essential task. In this section, we shall gradually move on to study
all these essential prerequisites.
8.1.1 Install R in Your System
• R 3.5.0 or higher (https://cran.r-project.org/bin/windows/base/)
• RStudio 1.1.453 or higher (Optional, only if you want to leverage the advantage of using an IDE.
Otherwise, R console is sufficient.) (https://www.rstudio.com/products/rstudio/download/)

Points to Ponder
❐ The Comprehensive R Archive Network (CRAN) is a network of FTP and web servers around the
world that store identical and up-to-date versions of code and documentation for R.
❐ RStudio is a free and open-source integrated development environment (IDE) for R.
8.1.2 Know How to Manage R Scripts
• Open new/pre-existing scripts in R console as shown in Figure 8.1.
