How to add vector {Any} as new line do dlm files?

vectors with numbers are writable byt vectors with string not ! How to write as new line to existing dlm file any vector from Array{Any} ?

julia> open("mytestfile.txt", "a") do io
       writedlm(io, A[2,:]')

julia> A
3×3 Array{Any,2}:
  "a"   "a"   "a"
 2     2     2
 3     3     3

julia> open("mytestfile.txt", "a") do io
       writedlm(io, A[1,:]')
ERROR: MethodError: no method matching adjoint(::String)

This has nothing to do with writedlm. Use permutedims instead of '.

Yes, but in this way row of array is saved as column !

2	2	2

How to add rows as rows ?

Use an 1xn matrix as the argument, eg

julia> writedlm(stdout, fill("a", 1, 3))
a       a       a
