Hello, I found a code to produce a histogram at
http://code.jsoftware.com/wiki/Essays/Histogram. However, both the description and the function seem odd. The code reads histogram=: <: @ (#/.~) @ (i.@#@[ , I.) 1) They say: ---The left argument is a list of interval *start* points.---, which I think is not quite right (or is at least deceptive): 2 3 histogram 1 1 0 2 3 histogram 2 1 0 (thus x are actually inclusive endpoints). 2) Furthemore and more importantly: 2 histogram 1 1 2 histogram 10 0 0 which (the 2nd case) is not nice, since the shape of the result changes depending on data *value*. I'd rather have a verb that would output 2 hist 1 1 0 2 hist 10 0 1 Does anyone have a verb like that? (I will try to design one myself, but am asking anyway.)
