Thank you everyone. Try executing this: replicate(100, length(hist(rnorm(100), nclass = 10)$counts)) I'm still not sure why the number of bins (classes) is not consistent.
R is behaving as documented. You suggested 10 bins, but it finds for some datasets that a smaller or larger number gives better results. If you really want exactly 10 bins, then specify where you want them.
