Let me add a thought here. I also think that adding a row to a dataframe should be easier. However, I do not think that an array would be the best container to represent a row because array members must all be of the same type which brings up Any as the only options in your example.
I think that appending or pushing a tuple with the right types could be made to work. So it would be julia> push!(psispread, (1.0,0.1,:Fake)) or julia> append!(psispread, (1.0,0.1,:Fake)) since julia> typeof((1.0, 0.1, :fake)) (Float64,Float64,Symbol) Note, I am not saying that this works now but that it could be made to work by adding the corresponding method to either function. It seems it is the right construct. Any thoughts?
