Remember that to print an object you can use the command print or simply type the object. Define p as one of the following:

p <- ggplot(data = murders)
p <- ggplot(murders)
p <- murders %>% ggplot()

What happens when printing p?

  1. Nothing happens.
  2. A blank slate plot.
  3. A scatterplot.
  4. A histogram.

Type your answer (1, 2, 3 or 4) in the terminal.
