Setting themes
Reusing a theme across many plots helps to provide a consistent style. You have several options for this.
- Assign the theme to a variable, and add it to each plot.
- Set your theme as the default using
theme_set().
A good strategy that you'll use here is to begin with a built-in theme then modify it.
plt_prop_unemployed_over_time is available. The theme you made earlier is shown in the sample code.

# Save the theme as theme_recession
___ <- theme(
rect = element_rect(fill = "grey92"),
legend.key = element_rect(color = NA),
axis.ticks = element_blank(),
panel.grid = element_blank(),
panel.grid.major.y = element_line(color = "white", size = 0.5, linetype = "dotted"),
axis.text = element_text(color = "grey25"),
plot.title = element_text(face = "italic", size = 16),
legend.position = c(0.6, 0.1)
)
# Combine the Tufte theme with theme_recession
theme_tufte_recession <- ___
