Hi! Welcome to Vertabelo Academy's Data Manipulation in R course. In this course, you'll learn what clean data is and some new ways of importing data – an essential everyday skill for people who work with data.

Data is often corrupted (i.e., with mistakes) or is given to us in an incorrect format. We need to fix these problems before we can work with it! In upcoming parts, we'll focus on different data problems and how to deal with them.

In this part, we'll learn how to read data into memory so we can work on it in R. This may not sound exciting, but without reading data we wouldn't be able to do much!

There are many different R functions that import data. In this course, we'll focus on the most popular ones. As we learn these functions, we'll work with CSV files, delimited files, Excel files. Don't worry if you're not familiar with any of these terms; we'll explain them as we go along.
