Hi I'm looking for the best way to count how many times a certain value x_i appears in vector x, where x could be integers, floats, strings. In R I would do table(x). I found StatsBase.counts(x,k) but I'm a bit confused by k (where k goes into 1:k, i.e. the vector is scanned to find how many elements locate at each point of 1:k). most of the times I don't know k, and in fact I would do table(x) just to find out what k was. Apart from that, I don't think I could use this with strings, as I can't construct a range object from strings.
I'm wondering whether a method StatsBase.counts(x::Vector) just returning the frequency of each element appearing would be useful. The same applies to Base.hist if I understand correctly. I just don't want to have to specify the edges of bins.
