Using your new knowledge about function definitions, create a function named theme_ilo() that encapsulates your theme settings.
The function body should contain both theme() calls that you would normally apply directly to a plot object: theme_minimal() + your customized theme() function.
Copy what you did before into this theme_ilo() function, using the theme() settings provided in the sample code.
