In this tutorial, we learn how to read data into R. In other words, we learn how to import data from a data file (specifically a .csv file) into R so that we can manipulate, manage, and analyze the data. R is in many cases case and space sensitive, meaning that upper- and lower-case letters hold meaning, as do the presence (or lack) of spaces in an object name. We learn how to read in your data in .csv format (which is the file format we use throughout this course) using the read.csv function from base R as well as the Read function from the lessR package. For this course, I encourage you to use the function read.csv because it does not require accessing a specific package. Finally, in this tutorial, we also learn how to set our working directory using the setwd function and how to install and access the functions in a particular R package using the install.packages and library functions, respectively.
