1.why does this code not work?

because in my_variable theres a 1 instead of an i in variable

2.tweak each of th R commands so they run properly

ggplot(data = mpg) + 
  geom_point(mapping = aes(x = displ, y = hwy))

3.Press Alt + Shift + K. What happens? How can you get to the same place using the menus?

i have no idea pretty cool tho

4.Let’s revisit an exercise from the Section 2.6. Run the following lines of code. Which of the two plots is saved as mpg-plot.png? Why?

the my_bar_plot is saved because thats what was specified

my_bar_plot <- ggplot(mpg, aes(x = class)) +
  geom_bar()
my_scatter_plot <- ggplot(mpg, aes(x = cty, y = hwy)) +
  geom_point()
ggsave(filename = "mpg-plot.png", plot = my_bar_plot)
