Hi all,

New to Julia and seeking a little help. I am working with a dataframe and for each row, I want to return either the position of the lowest n values, or the column names of the lowest n value. The package DataStructures (Heaps · DataStructures.jl) has a function that does this, but I really want to avoid loading a package just for this, as I’m sure the solution is relatively simple.

Say my dataframe was as follows:

```
df = DataFrame((name=["S1","S2","S3","S4","S5"],Z1=[41,12,19,17,11],Z2=[13,28,29,99,41],Z3=[7,86,23,12,71],Z4=[4,13,23,11,19],Z5=[41,12,13,19,22],Z6=[11,18,22,46,5]))
```

And if I were looking for the lowest 2 values, the result would be as follows:

```
df_sorted = DataFrame((name=["S1","S2","S3","S4","S5"],x1=["Z4","Z1","Z5","Z4","Z6"],x2=["Z3","Z5","Z1","Z3","Z1"]))
```

I thought maybe a combination of eachrow() and PartialQuickSort might do the trick, e.g.:

```
sort(eachrow(Matrix(df)),alg=PartialQuickSort(2))
```

But this results in an error.

If anyone has any suggestions, I would very much appreciate it. Thanks for your help!
