If I create an empty vector to hold DataFrames:

`vecOfDFs = Vector{DataFrame}[]`

(is that an ok way to do it? Are there better ways? )

And then I use `push!(vecOfDFs, myNewDF)`

to add my `myNewDF`

to `vecOfDFs`

I get the error

MethodError: Cannot `convert`

an object of type DataFrame to an object of type Array{DataFrame,1}
