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’.

The ’Appearance’ category has been selected, and three selectable options appear to the right, ’Rstudio theme’, ’Editor font size’, and ’Editor theme’. This last one has a long list of options, of which ’Tomorrow Night Bright’ has been selected. A preview of the theme appears to the right.
