Well, there's a slightly nicer way than that! (Don't forget that we're competing with Excel here ... ). Since the value of hist() includes breakpoints and counts, you can get the plot and the table as follows: set.seed(54321) X <- 5*rnorm(500) H<-hist(X) ### Here you get the histogram drawn B<-H$breaks ; C<-H$counts ; k<-length(B) cbind(From=B[1:(k-1)],To=B[2:k],Count=C) ### Here bins and frequencies # From To Count #[1,] -15 -10 16 #[2,] -10 -5 69 #[3,] -5 0 181 #[4,] 0 5 149 #[5,] 5 10 71 #[6,] 10 15 14 So we can indeed "get the table of bin and frequency like in excel, together with the histogram".
