Exercise 7. geom_point text

If instead of points we want to add text, we can use the geom_text() or geom_label() geometries. However, note that 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

Why is this?

We need to map a character to each point through the label argument in aes

We need to let geom_label know what character to use in the plot

The geom_label geometry does not require x-axis and y-axis values.

geom_label is not a ggplot2 command
