if you add 'plot=FALSE', like this:

hist(rnorm(100),plot=FALSE)

instead of plotting the histogram, you get a list of values. The  
component $counts
contains what you're looking for.

You can give it a name: a<-hist(rnorm(100),plot=FALSE), and treat it  
like any other list.
(if you do "a<-hist(rnorm(100))" then you get both the values and the plot)

check ?hist for details.
