To add a row, you can merge 2 dataframes :

```julia
 julia> df = DataFrame(A = 1:4, B = ["M", "F", "F", "M"])
4×2 DataFrames.DataFrame
│ Row │ A │ B │
├─────┼───┼─────┤
│ 1 │ 1 │ "M" │
│ 2 │ 2 │ "F" │
│ 3 │ 3 │ "F" │
│ 4 │ 4 │ "M" │

julia> df2 = DataFrame(A = 6, B = ["F"])
1×2 DataFrames.DataFrame
│ Row │ A │ B │
├─────┼───┼─────┤
│ 1 │ 6 │ "F" │

julia> append!(df,df2)
5×2 DataFrames.DataFrame
│ Row │ A │ B │
├─────┼───┼─────┤
│ 1 │ 1 │ "M" │
│ 2 │ 2 │ "F" │
│ 3 │ 3 │ "F" │
│ 4 │ 4 │ "M" │
│ 5 │ 6 │ "F" │

```
