6). Then, click Import. RStudio will run all of the code in the preview box. This imports the data using the read_csv() function from the readr library. It also opens a window showing the data. Close that window - you don’t need it open. Now, paste the two lines of code into your script. Having done this, you don’t have to use the Import Dataset tool again. You just run these lines of code and your data are read in (assuming you don’t move the data . . ). Your script now contains the information about which dataset is being used and where it is on your computer.

To see the script pane, you need to look in the upper right corner of the Console pane that is dominating your screen. Up there, on the right, you should see two squares overlapping each other. Go on. Press them. All of a sudden, like magic (we all need magic), there should be two panes on the left. 7). From now on, when you open RStudio, there will be four panes, not three.
