In this chapter, we have learned about the benefits that EDA can bring to businesses across various verticals. We introduced the R packages that will be used in this book to teach concepts related to EDA. We also learned how to set up and install these packages using both the Terminal and RStudio.
The next chapter will demonstrate practical, hands-on code examples that show how to handle reading all kinds of data into R for EDA. We will cover how to use advanced options while importing datasets, including delimited data, Excel data, JSON data, and data from web APIs. We will also look at how to scrape and read in data from the web and how to connect to relational databases from R. We will use R packages such as readr, readxl, jsonlite, httr, rvest, and DBI.
