If instead of points we want to add text, we can use the
geom_text() or geom_label() geometries. The following code
murders %>% ggplot(aes(population, total)) + geom_label()
will give us the error message: Error: geom_label requires the
following missing aesthetics: label. This is because we need to specify
which labels it should print throug the label aestethic mapping.
1. Rewrite the code above to use abbreviation as the label through
aes. Save the resulting ggplot object in p_abb.
2. If we wanted to change the color of the labels to blue, how would we do that?
blue to murders.aes.color argument in ggplot.geom_label.Save your answer in question_2
3. Rewrite the code above to make the labels blue.
Save the resulting ggplot object in p_abb_blue
