Same code different plot in qplot vs ggplot

Question

I get very different results, the code should be equivalent?

qplot(x = price, data = diamonds) + facet_wrap(~cut)

vs

ggplot(aes(x = diamonds$price), data = diamonds) + geom_histogram()  + facet_wrap(~cut)

try this instead

ggplot(aes(x = price), data = diamonds) + geom_histogram()  + facet_wrap(~cut)

Exactly, $ has no place inside aes since ggplot2 does non-standard evaluation. It looks for variables inside the declared data.
