Y-axis Scale Number in the Millions

Question

I am trying to edit the Y-axis scale to represent the amount the rows of Id. The numbers needed to be shown on the scale are in the millions. I need to abbreviate the number in order for it to be seen on the visualization.

  ggplot(sleeptocalories1, aes(Id,TotalCalories) +
  geom_col(fill="steelblue") +
  theme(axis.text.x = element_text(angle = 90)) +
  theme(axis.text.y = element_text(angle = 45)) 

Answer 1

I like scales::label_number_si():

ggplot(data.frame(x = 1:5, y = 10^(2:6)), aes(x, y)) +
  geom_col() +
  scale_y_continuous(labels = scales::label_number_si())

On your data, it might be:

ggplot(sleeptocalories1, aes(Id,TotalCalories) +
  geom_col(fill="steelblue") +
  theme(axis.text.x = element_text(angle = 90)) +
  theme(axis.text.y = element_text(angle = 45)) + 
  scale_y_continuous(labels = scales::label_number_si())
