Add facets to the plot
Here, you'll leverage facet_grid() to add horizontal facets for 1996 and 2006 each, as detailed in the video.
When using facet_grid(), it is good practice to specify the arrangement of plots with a named argument: rows = ... or cols = .... This helps to avoid confusion since the facet_grid() function takes many other arguments.
This exercise is part of the course
Communicating with Data in the Tidyverse
Exercise instructions
- Use
facet_grid()with the right argument to generate two separate scatter plots that are arranged horizontally. - The left plot should show the data for the year 1996 while the year 2006 should be shown on the right side.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Again, you save the plot object into a variable so you can save typing later on
ilo_plot <- ggplot(ilo_data, aes(x = working_hours, y = hourly_compensation)) +
geom_point() +
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"
) +
# Add facets here
