Section A.2 Customising the RStudio look
RStudio allows you to customise the way it looks. Working with white backgrounds is not generally a good idea if you care about your eyesight. If you don’t want to end up with dry eyes, not only it is good that you follow the 20-20-20 rule (every 20 minutes, look for 20 seconds to an object located 20 feet away from you), but it may also be a good idea to use more eye-friendly screen displays.
Click in the Tools menu and select Global Options. This will open up a pop-up window with various options. Select Appearance. In this section you can change the font type and size, but also the kind of theme background that R will use in the various windows.

You can make any changes you’d like to here, including the theme background that
R will use as the interface. For example, you may choose a darker theme like ’tomorrow night bright’.
