Environment setup
We will be using several R libraries or packages in this chapter as mentioned before. The major libraries which will be used along with their main utility are outlined in the following table. Feel free to use install.packages(…)
to install them. For ease of usage, I have also created a file called env_setup.R
which you can load into R and execute the necessary code present there to install all the necessary packages which will be used in this chapter. You can also find the package descriptions in more detail from the CRAN website at https://cran.r-project.org/web/packages/available_packages_by_name.html:
