Hi,
A few weeks ago there was a discussion about a
histogram_discrete() function --sorry for starting a new
thread but I have lost the mails.
Somebody pointed out that bincount() already can be used
to histogram discrete data (except that it doesn't work
with negative values).
I have just discovered a function in scipy.stats called
itemfreq() that does handle negative values.
In [17]: scipy.stats.itemfreq([-1,-1,0,5])
Out[17]:
array([[-1., 2.],
[ 0., 1.],
[ 5., 1.]])
Bye.
