How to calculate the mode of an array in Julia?

Question

I have an array defined as the following:

julia> a = [5, 6, 7, 8, 10, 12, 12, 17, 67, 68, 69, 72, 74, 74, 92, 93, 100, 105, 110, 120, 124]
21-element Vector{Int64}:
   5
   6
   7
   8
  10
  12
  12
  17
  67
  68
   ⋮
  74
  74
  92
  93
 100
 105
 110
 120
 124

I am able to calculate the standard deviation but there does not seem to be a mode function built into Julia like there is with the std() function.

Answer 1

While there is no built in function to do this, the mode function does exist in the StatsBase package:

julia> using StatsBase

julia> mode(a)
12
