交互式实操练习
通过完成这段示例代码来试试这个练习。
# Save your current plot into a variable: ilo_plot
___ <- ggplot(plot_data) +
geom_point(aes(x = working_hours, y = hourly_compensation)) +
labs(
x = "Working hours per week",
y = "Hourly compensation",
title = "The more people work, the less compensation they seem to receive",
subtitle = "Working hours and hourly compensation in European countries, 2006",
caption = "Data source: ILO, 2017"
)
# View it
