[julia-users] Best way to convert Any of vectors into matrix

[Bradley Setzler]

Good evening,

I often have Any types filled with vectors (especially as the return of a 
pmap), and need them as a matrix or DataFrame. For example, suppose I have,

julia> A
3-element Array{Any,1}: 
[1,2] 
[3,4] 
[5,6]

But I want,

julia> B
2x3 Array{Int64,2}: 
1 3 5 
2 4 6

I came up with the following, which successfully constructs B from A, but 
it's a bit inefficient/messy:

B = A[1]
for i=2:length(A)
    B = hcat(B,A[i])
end

Is there a better way to do this? Something like,
julia> B = hcatForAny(A)

Thanks,
Bradley
