Come inserire file

First, you do not need to remember the setwd function. Second, you will not make typos in the path of your folder path which can sometimes be quite long if you have folders inside folders. Third, when saving your script which I assume you do otherwise you would lose all your work , you also save the actions you just made via the buttons.

So when you reopen your script in the future, no matter what is the current directory, by executing your script which now include the line of code for setting the working directory , you will at the same time specify the working directory you selected for this project. Now that you have transformed your Excel file into a CSV file and you have specified the folder containing your data by setting the working directory, you are now ready to actually import your dataset.

Remind that there are a two methods to import a file:. No matter which method you choose, it is a good practice to first open your file in TextEdit on Mac or Notepad on Windows in order to see the raw data. If you open the file in Excel you will see the data already formatted and thus miss some important information needed for the importation. Below an example of raw data:. From this window, you can have a preview of your data, and more importantly, check whether your data seems to have been imported correctly.

Below, the import options you will most likely use:. You should now see your dataset in a new window and from there you can start analyzing your data.

This user-friendly method has the advantage that you do not need to remember the code see the next section for the entire code. However, the main drawback is that your import options will not be saved for a future usage so you will need to import your dataset manually each time you open RStudio. Similarly to setting the working directory, I also recommend using the text editor instead of the user-friendly method for the simple reason that you can save your import options when using the text editor and not when using the user-friendly method.

Saving your import options in your script thanks to a line of code allows you to quickly import your dataset the exact same way without having to repeat all the necessary steps every time you import your dataset. The command to import a CSV file is read. Here is an example with the same file than in the user-friendly method:. After the importation you can check whether your data have been correctly imported by running View dat where dat is the name you chose for your data. A window, similar than for the user-friendly method, will display your data.
