Instruções do exercício

  • 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.

# For a starter, let's look at what you did before: adding various theme calls to your plot object
ilo_plot +
  theme_minimal() +
  theme(
    text = element_text(family = "Bookman", color = "gray25"),
    plot.subtitle = element_text(size = 12),
    plot.caption = element_text(color = "gray30"),
    plot.background = element_rect(fill = "gray95"),
    plot.margin = unit(c(5, 10, 5, 10), units = "mm")
  )
      
# Define your own theme function below
theme_ilo <- function() {
    ___() +
    ___(
        ___
    )
