titles and axis labels

Titles and axis labels are easy to add and change in ggplot! We simply add another line to our code. NOTE you can also add a subtitle, caption, or change the legend title using labs!

ggplot(data=penguins, aes(x=species, y= bill_length_mm)) +
  geom_boxplot(aes(fill=species))+
  scale_fill_aaas()+
  theme_classic()+
  labs(x = 'Species', y='Bill length (mm)', title='Penguin bill length by species', fill='Species')+ #here I change the x-axis and y-axis labels, add a title, and change the legend label (to capitalize the 'S' in 'species')
  theme(text=element_text(size=18))

Warning: Removed 2 rows containing non-finite values (`stat_boxplot()`).
