I’m sorry for necroing a thread that is over 6 years old, but I want to add that the comment marked “solution” will throw an error.

For an empty `DataFrame`, bkamins’ first comment works, but for an unitialised `DataFrame` of length `N`, as explained in [another thread](https://discourse.julialang.org/t/how-to-initialize-empty-dataframe-of-specified-size/67421/4), it’s far better to construct and populate the individual columns as length `N` `Vector`s first, then construct the DataFrame from these vectors.
