Count instances of each unique integer in a vector in 1 line of code?

Question

Is there a slick way to rewrite this Julia function, perhaps using just 1 line of code, without making it much slower? (I just started using Julia. It\'s great!) K

Answer 1

There are a bunch of counting functions included in the StatsBase.jl package. Your tally function is equivalent to counts(zd, 1:K).

There are also methods for counting unique elements of types other than integer, too, such as countmap, which returns a dictionary mapping unique values to their number of occurrences.
