normal prob plot in lab 4

[betahat]

In lab 4 problem 3, it says:

3. Make a normal probability plot of sim_norm. Do all of the points fall on the line? How does this plot compare to the probability plot for the real data? (Since sim_norm is not a dataframe, it can be put directly into the sample argument and the data argument can be dropped.)

Probably a change in ggplot, but it looks like ggplot can't accept a vector as an argument, but geom_line can. So it seems that options could either be to have the parenthetical include a point about moving aes to the geom instead of the ggplot, or coercing the vector into a data frame when it's created.
