Add method to writetable for DataArray?

[randyzwitch]

It seems weird that you can only export a DataFrame and not a DataArray from within DataFrames (i.e. you have to use writedlm from Base to export an array). We could do:

function writetable(filename::String,
                    df::DataArray;
                    header::Bool = true,
                    separator::Char = getseparator(filename),
                    quotemark::Char = '"')
    io = open(filename, "w")
    printtable(io,
               DataFrame(df),
               separator = separator,
               quotemark = quotemark,
               header = header)
    close(io)
    return
end

Or, we could modify printtable to have a DataArray method to avoid the DataFrame(df) type conversion.

Of course, if I'm the only one that sees this as an issue, we can do nothing.

Only tangentially relevant, but @johnmyleswhite and I were just talking about the idea of splitting the DataArray type out if DataFrames into its own package (presumably called DataArrays). I think that we should definitely do this.

Really? What would be returned when you index a single column from a DataFrame? Would it just be an n x 1 DataFrame

[StefanKarpinski]

DataFrames would depend on DataArrays but not vice versa. The pint is that there are use cases for the relatively simple functionality of DataArrays without all the rest of DataFrames.

I vote to break DataArrays out from DataFrames.

Thanks @StefanKarpinski, that makes sense.
