How to load core tidyverse packages into the R session?

This post is part of 'SASnR | Introduction ' series

By default, the installed packages are not automatically loaded into an R session. The required packages need to be explicitly loaded using library function.

All the core packages of tidyverse can be loaded with the below line of code.
