To be more precise, when using hist(prob=T) the y axis shows the densities.
If you want relative frequencies (proportions) you can use the histogram(x,
type=) function in the package lattice or write your own function.

The one key thing here is not to forget "prob=TRUE" in the call to hist(),
to
ensure that the y-axis is scaled in proportions, not in frequencies.
